### *Why this commit*: 
---
Ensures Quality Checks and Mass Produce options remain available on the
Shop Floor regardless of the "Auto-close Production" setting.

### *Steps to Reproduce*
---
1. Define a product tracked by Serial Numbers with a Manufacturing BoM.

2. Create a Quality Control Point for the product on the Manufacturing
operation.

3. In Inventory Configuration, disable "Auto-close Production" on the
Manufacturing operation type.

4. Create a Manufacturing Order (MO) and open it in the Shop Floor view.

5. If the MO has no operations, try to use Mass Produce.

### *Before this PR*
---
When auto_close_production was set to False, the Shop Floor card footer
incorrectly hid both the Quality Checks and Mass Produce buttons.
This blocked users from registering Serial Numbers and completing mandatory
quality check steps.

Additionally, for products without BoM operations, clicking Mass Produce 
triggered quality check validation instead leading to errors, preventing the
generation of serial numbers.


### *After this PR*
---
The visibility logic for Shop Floor actions is now decoupled from the closing
permission. The workflow follows this corrected sequence:

Mass Produce: Stays visible to allow serial registration and backorder
creation even if the MO cannot be closed from the Shop Floor.

Quality Checks: Remain accessible to ensure all mandatory tests are
passed before production progresses.

Close Production: Only appears if "Auto-close Production" is enabled
on the operation type.

Steps to reproduce
1. Set the company's partner timezone to a negative UTC offset (e.g. America/Argentina/Buenos_Aires, UTC-3).
2. Create a sale order for a storable subscription product and confirm it.
3. Open the generated delivery order and check its Scheduled Date.

Issue
The scheduled date on the first delivery renders as the previous day. `_prepare_procurement_values` writes `date_planned` as `current_period_start`, which is a plain `fields.Date` value
(https://github.com/odoo/enterprise/blob/ba41d7de3c0474286e3e9319710fdacfb95d3e2c/sale_subscription_stock/models/sale_order_line.py#L156). When a `date` is stored in the `Datetime` column `stock.move.date`, Odoo anchors it at midnight UTC; in any negative-offset timezone this renders as the previous day (e.g. `2022-03-02 00:00 UTC` shows as `2022-03-01 21:00` in UTC-3). The non-subscription path does not hit this because it resolves `date_planned` through `_expected_date()`, which returns `order_id.date_order` — a full `Datetime` set to `fields.Datetime.now()` at confirmation (https://github.com/odoo/odoo/blob/996702b0d5c518db2ac6f0b144e7835b27c29736/addons/sale/models/sale_order_line.py#L1398).

The same midnight-UTC drift also affects later recurrences, where `current_period_start` falls back to `last_invoice_date` — another `Date`.

Solution
Split the two cases explicitly:
- First delivery (`last_invoice_date` unset): set `date_planned` to `order_id.date_order`, matching the non-subscription flow.
- Subsequent deliveries: localize `last_invoice_date` at `00:00` in the company timezone before converting back to UTC, reusing the pattern already applied to reordering rules (https://github.com/odoo/odoo/blob/20a0eee2d03293564320c268252a0353781d99ea/addons/stock/models/stock_orderpoint.py#L722).

Payment reminders are not sent to the duplicate of a subscription when a reminder has already been sent for the original subscription

Steps to reproduce:
1. Install Subscriptions
2. Create a new subscription for customer Acme Corporation with product Office Cleaning Service (SUB), a Monthly recurring plan and in the Other Info tab, set the subscription Start Date to one week ago
3. Confirm the subscription
4. Go to Scheduled Actions and run the action "Sale Subscription: send reminder for subscriptions with no token"
5. Go back to the previously created subscription (see that a reminder email has been added in the chatter)
6. Duplicate the subscription and confirm the duplicate
7. Run the action "Sale Subscription: send reminder for subscriptions with no token" again
8. There are no reminder for the duplicate subscription

Issue:
The copy of a subscription uses the same `last_reminder_date`, preventing payment reminders to be sent here
https://github.com/odoo/enterprise/blob/5a2ab62254cd5f684a3b1a0d7c0001b888c70d08/sale_subscription/models/sale_order.py#L2114-L2120

Solution:
Set `copy=False` on the field `last_reminder_date`

## Issue
In the *Sign* app, when attempting to download multiple documents with similar subjects, only one document appears in the resulting zip file.

## Steps to reproduce
1. Install *Sign* (`sign`)
2. Sign a same template twice, using the same subject S1. This gives us Documents D1 an D2.
3. (Optionally), sign the same template a third time, using a different subject S2, creating document D3.
4. In Sign > Documents, select the 2 (3) signed documents and click *Download*.
5. **In the resulting zip file, there's one folder S1 containing a single pdf document (D1) (and one folder S2 containing D3). Document D2 is missing from the zip file.**

## Cause
When generating the zip file, the path used for each document is `{subject}/{doc_name}`.

https://github.com/odoo/enterprise/blob/863abc99469c12acdebcab05788d566c370bb46f/sign/controllers/main.py#L276-L286

Neither of this attribute are unique, which means that two signed documents with the same name and subject can be downloaded simultaneously, but will then overwrite each other.

## Fix
Before version 18.3, the zip file would contain folders named with the (unique) request id, which would consistently make them distinct from one another. This behavior was changed by https://github.com/odoo/enterprise/commit/4254542e8fb4ce3b2b9b46c624d86f7fcac8df7b to use the `sign_request.subject` instead. This commit adds the `request.id` after the subject to keep the clarity of the subject, and add the uniqueness of the id.
