- Set the TZ as 'America/Martinique'
- In the calendar (month view), click on a date D.
- Fill in the topic, then click on "Edit"

The date is set to D-1.

Commit 09066fbb makes the date consistent when the user sets an
event as an all day event by taking into account the appropriate
timezone.

However, in the case of an event created from the month view, this TZ
modification should not be applied.

Before this commit, we could temporarily change cashier from A to B, and back to A seamlessly just by refreshing the page.
This could be a security issue for a cashier is held responsible for its sales.

This commit stores the cashier in localstorage, and with the right sets of methods, corrects the issue.

closes #19207

The default size limits set in base.sql are eventually superseded by the
actual limits (or absence of) when the DB schema is synchronized with
the Python model definitions.

However the list of modules (name, authors, descriptions, dependencies)
is loaded before this can happen. The length of the author field is one
case that can easily crash the database bootstrap process at that point,
should a module with a long author name be present in the addons path.

After schema sync, that size limit is lifted entirely (although Odoo Apps
does limit the max author name length to 512 at the moment, to prevent
abuse).

Fixes #5850

Closes #19231

Before this commit, a message received through the contact us form did create a Lead, but any notification was impossible (even if a user was a follower of the relevant sales team.
This was because the default sales team is integrated in the values for create in models.py, which mail_thread can't see, but needs in order to notify

This commit corrects the behavior which now converge with standard lead creation by adding the default sales_team earlier in the values for create

Done at #19025

When refunding an invoice with the option: "Cancel: create refund and reconcile",
it raised a warning: "You are trying to reconcile some entries that are already reconciled!"
because in some cases the refund is linked to several entries which match the same
account of the invoice. So it tried to reconcile several times the same entries.
