Currently, an error occurs when a user creates a 'Model Page', which is referring to a non-stored model and trying to access it through website view.

Steps to Reproduce:
- Install stock, website and web_studio modules.
- Open Inventory and turn on studio mode.
- Navigate to model pages.
- Create a new model page with the exposed model as 'Stock Quantity Report'.
- Save and click on the Website smart button and you will get the error.

Error:
`ValueError: Invalid field 'create_date' on model 'report.stock.quantity'`

Root Cause:
Odoo Studio allows creating website pages for any model, including non-stored models (`_auto = False`) such as `report.stock.quantity`. When a user creates a `Model Page` with such a model, Odoo attempts to fetch records from the database and sort them by `create_date` as shown at [1]. Since these models do not have a database table, the `create_date` field does not exist, causing the error.

Fix:
Exclude non-stored models from the model selection for Model Pages.

Steps to reproduce:
1. Install `marketing_automation`
2. Create a campaign with activity and click on `Launch a test` button
3. Clear the input field and then click outside the input area

Issue:
- The input area has disappeared. Now, the only way to get it back is by closing the dialog and reopening it

Cause:
- Field `resource_ref` uses `hide_model: True`, and when cleared, the widget has no value and no model selector to determine the target model because of the function `getRelation` that now returns `undefined`, by this XML fails to render the `<Many2OneField/>`
https://github.com/odoo/odoo/blob/7680b83501cef18362be38f90715d824f2bf9cd6/addons/web/static/src/views/fields/reference/reference_field.js#L107-L119

Solution:
- Add `model_field: model_id` option to the view so the widget can resolve the model from the `model_id` field even when input is empty

Note:
- This behavior also occurs in other places. After discussion with the framework team, we agreed to keep the scope of this PR limited to marketing_automation, as this is not a priority issue. A broader fix can be addressed in the master if needed.

1. Create a contact (with minimal details).
2. Create a customer invoice for that contact **last month** with `quantity = 300`.
3. Create a credit note for that invoice **this month**.
4. Create another customer invoice for the same contact **this month** with `quantity = 100`.

In the FAIA report (XML), within the General Ledger section, the partner is incorrectly classified as a supplier instead of a customer.

In the method _saft_fill_report_partner_ledger_values from account_saft, he partner type is determined based on whether the balance is negative.

However, a negative balance can result from a credit note, where the partner is still a customer and not a supplier. Furthermore, a partner can be both a supplier and a customer.

This commit allows a partner to be both a customer and a supplier. If both receivable and payable are 0 we set the partner type to customer to keep the behavior from e9640caf29e967fe7d8c6fe303b5a8d7a866437e

Steps to reproduce:
- Choose France as the company location, and download "France - Work Entries Time Off" module.
- From Employees > Configuration > Settings > French Time Off Localization, select Paid time Off.
- Create a new employee and a new contract (in running state) for that employee that starts on 01/01/2025.
- While in the contract screen, create a new schedule that has 2 weeks calendar and Europe/Paris timezone.
- From Time Off > Management > Allocations, allocate 1+ paid time off days for the newly created employee that's valid from 01/01/2025.
- From the employee's profile > Time Off, try to take a Monday off.

Issue:
- The user gets a Validation error stating that the "start date" is later than the "end date".

Fix:
- In a 2 weeks calendar, there are 2 lines that are there to separate the first week from the second week (for aesthetic purposes). These lines have "hour_from" and "hour_to" = 0, which are taken into account when calulating the minimum hour to start the day off.
- Add a check to remove lines from calendar that are just there for display purposes.
