Steps to reproduce:
-------------------------------------
1. Install `hr_holidays_attendance` module
2. Time off > configurations > Time off types
3. Create new time off type as follows:
* Set Approval to Approved by time off officer
* Change Take time off In to Hours
4. Save the record and enable Deduct Extra Hours
5. Go to Management > Allocations
6. Create new allocation with created time off type and select 'Audrey Peterson' in Employee
7. Try to save record > Validation Error > Discard changes
8. Change time off type to Paid Time Off > add 'Audrey Peterson' > save record
9. Now change Time Off type to Created Time Off type > Save

Observation:
-------------------------------------
No Validation Error raised, as the employee and time off type are still the same as they were during creating allocation.

Issue:
-------------------------------------
In `write` method, there was no any check for the employee if it has enough overtime hours when we change Time off type (`holiday_status_id`) to overtime-deductible leave type.

Check was only present in the `create` method:
https://github.com/odoo/odoo/blob/a95c639db68f98351c7162de58a041a1c0ee13c5/addons/hr_holidays_attendance/models/hr_leave_allocation.py#L39-L49

Solution:
-------------------------------------
1. Create new function for validate overtime and to create adjustment
2. Added that function to `create` as well as in `write` method
3. Prevents creating a duplicate overtime adjustment for an allocation that already has one

Before this change, the "Outlook: synchronization" cron would not create calendar events on Outlook's side in _sync_odoo2microsoft due to a filter for calendar.events written to within 5 minutes of microsoft_last_sync_date, when _sync_data is not called when a calendar.event is created, such as through website.appointment. microsoft_last_sync_date was set to datetime.now() at the beginning of _sync_microsoft_calendar, which would skip a large period of time between the last sync and now, if the only syncs were triggered through cron, and not _sync_data (by opening the calendar app).

To reproduce, 

Default "Outlook: synchronization" is ran every 12 hours. 

1) Calendar event is synced through "Outlook: synchronization" cron at 00:00, setting microsoft_last_sync_date to 00:00
2) A website.appointment is created for a resource with Outlook calendar sync enabled any time between 00:01 - 11:54. 
3) "Outlook: synchronization" runs again at 12:00, which sets microsoft_last_sync_date to 12:00, and filters out calendar.events based on their write_dates in _extend_microsoft_domain that need syncing outside of 11:55 to 12:00. 

This change removes setting of microsoft_last_sync_date at the beginning of _sync_microsoft_calendar, where we need to use the old value before setting it at the end of _sync_microsoft_calendar.

[FIX] mail: ensure all mailservers are fetched by fetchmail service
The Scheduled Action Mail: Fetchmail Service sometimes ignored incoming mail servers when there were many servers.

Steps to reproduce:
-Ensure mail is installed
-Create at least 15 incoming mail servers
-Set one server to priority 10 (the default priority is 5)
-Run the Mail: Fetchmail Service Scheduled Action multiple times
-Observe that when it takes longer than 10 seconds to check all mail servers, we never check low priority servers.

This commit introduces a method to sort servers in order of urgency, which ensures all servers are checked while respecting priority.

Priority difference: We calculate the priority difference by taking the log of the number of servers. For example, 10 servers will
have a difference of 1 minute between priority levels, while 50 servers will have a difference of 1.7 minutes between levels.
We use the current fetchmail cron interval as the base interval. This base interval is used as the target interval for
priority 1 servers, while the target interval for priority n servers = base interval + ((n - 1) * priority difference).
The logarithmic scaling ensures that the priority difference grows with the number of servers without becoming too large.

For example, given a base interval of 5 minutes and a priority difference of 1 minute, a priority 1 server has a target interval
of 5 minutes, while a priority 10 server has a target interval of 5 + (9 * 1) = 14 minutes.

Urgency ratio: The urgency ratio for a server is calculated by comparing the time since the server was last
checked to the server's target interval.

For example, a priority 1 server that was checked 5 minutes ago with a target interval of 5 minutes has an urgency ratio of
5 / 5  = 1.0. Meanwhile, a priority 10 server that was last checked 15 minutes ago with a target interval of 14 minutes has
an urgency ratio of 15 / 14 = 1.07. The urgency ratio of 1.07 puts the priority 10 server as more urgent than the priority
1 server with an urgency ratio of 1.0.

The urgency-based queue reacts well under load: if we experience a delay of 10 minutes, the priority 1 server now has an
urgency ratio of 15 / 5 = 3.0, which we will check before the priority 10 server that now has an urgency ratio of 25 / 14 = 1.79.

When settling a sale order in POS after validating the delivery, quantities and lots were wrong for lot-tracked products with warehouse "Pick then Deliver (2 steps)": quantity doubled when loading SN/Lots.

Steps to reproduce:
-------------------
* Create a product with Tracking by lots
* In Inventory, set warehouse Outgoing Shipments to "Pick then Deliver (2 steps)"
* Create a quotation with the product and confirm it
* Validate the delivery
* In POS, settle the sale order from Quotation/Order
* When asked "Do you want to load the SN/Lots linked to the Sales Order?", click Yes

> Observation:
Quantity doubled.

Why the fix:
------------
read_converted() used move_line_ids from all moves linked to the sale line. With 2-step, both pick and delivery moves have move_line_ids with the same lots, so quantities were counted twice.
We now use move lines from exactly one picking and filter by sale_line_id.

**Steps to reproduce:**
- create a storable product avco auto 
- make sure that a purchase tax is set in 'General Information'
- create and confirm a PO for 30 quantities with a price of 0
- receive the products
- create and validate a delivery for 10 units of the product
- from the PO create the bill 
- set a date and save
- set a price of 100
- on the Bill set the total tax at 500 (it's bellow 'untaxed amount' 
on the bottom right of the bill and should be 450 before you 
change it, if the tax is 15%)
- confirm the bill

**Current behavior:**
The total tax was reset to 450

**Expected behavior:**
It should stay 500 as it was manually set

**Cause of the issue:**
The total tax amount is computed based on the tax lines 
in Journal Items
https://github.com/odoo/odoo/blob/2744396733bb3ad60813e9e093d67192c0d38b36/addons/account/models/account_move.py#L1171
So the problem is actually that a recomputation of the balance
of the tax account.move.line (the one with the account "tax paid" in 
journal items) is triggered when we confirm the Bill.

That's because :
When we confirm the bill, because the price is different than 
the one on the PO, _apply_price_difference does 2 things : 
(1) it creates an svl (with corresponding amls) for the quantities
that are still in stock (here 20)
(2) it adds amls on the bill (crediting stock interim received and 
debiting expense) to compensate the cogs deficit for the already 
out of stock quantities (here 10).
cf https://github.com/odoo/odoo/pull/126536 for more details

When we create those amls from (2),  the create method 
from account.move.lines calls super() inside a context manager 
calling _sync_dynamic_lines().
https://github.com/odoo/odoo/blob/5583cbcebae00d8122dce5ce929b650929966a90/addons/account/models/account_move_line.py#L1628-L1635
the yield of sync_dynamic_lines() is inside a context manager
calling _sync_tax_lines.
https://github.com/odoo/odoo/blob/5583cbcebae00d8122dce5ce929b650929966a90/addons/account/models/account_move.py#L3250
Therefore, the first half of sync_tax_lines() (untill the yield) is ran 
before the call to super and the rest (from the yield) is ran 
after the call to super. 
Because we added two lines in the account.move, get_changed_lines
will return those 2 new line and because there is a tax_ids on the new lines
round_from_tax will be False.
https://github.com/odoo/odoo/blob/5583cbcebae00d8122dce5ce929b650929966a90/addons/account/models/account_move.py#L3034-L3041
Therefore we won't reach continue.
https://github.com/odoo/odoo/blob/73d73c5c6606e0b34c754bfc4de035840951dd3b/addons/account/models/account_move.py#L3055-L3059
And the tax line will be recomputed using 
_prepare_tax_line()
https://github.com/odoo/odoo/blob/73d73c5c6606e0b34c754bfc4de035840951dd3b/addons/account/models/account_move.py#L3065

Here is why there is a tax_ids on the new lines : 
The field is precompute so if we don't set a value for 
it, _compute_tax_ids will be ran to compute it.
As the account move on which the lines are added 
is a bill, the tax_ids will the supplier_tax_id of the product.
https://github.com/odoo/odoo/blob/73d73c5c6606e0b34c754bfc4de035840951dd3b/addons/account/models/account_move_line.py#L898-L901

**Fix:**
There is no need for a tax_ids on these lines as they 
are not meant to (and should'nt) impact the taxes.

During the upgrade from XML-based feeds to the new JSON Listings API for stock management, we chose to use Amazon's API to fetch a listing's fulfillment channel information. However, Amazon does not provide a clear answer for a given listing. After some research, we assumed an offer was FBM when the listing contained a `merchant_shipping_group`, because this setting is specific to FBM listings. See also e6d620e4b200cadabb00ce37ab03289cfeb4ae58.

This assumption was flawed: Amazon can keep the shipping group even after a listing switches to FBA, which can block stock synchronization.

This commit uses the `fulfillmentAvailability` field from the Listings API instead. This field stores the available quantity for each fulfillment channel in which the listing is sold.

When multiple fulfillment channels are present, the offer defaults to FBM so stock synchronization can continue. The
`sale_amazon_channel_management` module can then be installed to manually select and disambiguate the channel.

This commit also upgrades the patching method used to update the FBM stock to ensure user specific configuration aren't overriden during the synchronization.
