While trying to fix the SAT cron, we did not think it through
it could cause infinite cron triggering.
Indeed, the write_date is updated on every record that is handled.

Fix is manyfold:
- Avoid re-processing what we already check within the last 4 hours/12 hours
depending on the type of the document.
- The domain takes the *static* create date instead of the write_date
to make sure we don't endless re-process the same record and that
the window of 7/60 days applies.
- Limit the Vendor Bill to be checked only during 7 days after their creation.
- Use the create_date in the order of the search to ensure we process older
records first, before their time-window closes.
- Process the Vendor Bills last, this ensure Customer Invoices will be processed
in priority in case we are not able to process everything within the last 4/12 hours.

This is still imperfect and a little fragile, we will find a better solution
in master, most likely by adding a dedicated field to keep track of the
last SAT check.

When importing a WinBooks zip, contacts sharing the same number might fail VAT validation if distinct contact data is merged incorrectly.

Steps to reproduce:
- Create a database with the Belgian localization installed
- Install the account_winbooks_import module
- Navigate to Accounting > Configuration > Settings > Initial Setup > Import
- Import the WinBooks zip

Issue:

The import fails with the following error:
The VAT number [AAAAAA] for partner [BBBBBB] does not seem to be valid. Note: the expected format is BExxxxxxx.

Analysis:
In WinBooks, contacts can be of type Supplier or Customer, and it is possible for a supplier and a customer to share the same number. During the import, the system will merge contacts if found with the same number.

In the specific case, the VAT number from one contact without country is combined with the country information from another contact, resulting in a VAT validation error.
This change prevents the merger of partner data if their VAT numbers are explicitly different.
