This update improves how Odoo manages database checkpoints during operations, ensuring temporary changes are properly cleaned up when a process finishes. This helps reduce hidden database state issues and makes imports, tests, and internal processing more reliable.

Ensure savepoints are *always* released when exiting the context: rolling back to a savepoint does not release it, so the savepoint remains "active" forever (just possibly shadowed if an other savepoint of the same name gets created).

Also provide a `Savepoint` object to the user, with the followingfacilities:

* `name`, in case there are useful things the user can do with a savepoint name.
* `rollback` allows the user to rollback the savepoint to the initialisation state at any moment.
* `close` allows the use of `contextlib.closing` as well as closing the savepoint while in the covered span. Closing a savepoint rolls it back by default (like cursors).

  Because there's no such thing as committing a savepoint, it's also possible to close *without* rolling back, which is similar (but not identical).

NOTE: unlike some other constructs, the `Savepoint` object has no effect before the context is entered.

Also make a `flushing` context manager for convenience, and provide a home-grown version of `contextlib.nullcontext` as that requires 3.7.

Project task forms now show a quick count of tasks that depend on the current task. This helps teams understand what work is being held up and prioritize tasks that unblock others.

This commit adds a stat button representing the number of dependent
tasks, the current task is blocking.

This is the inverse relation of "Blocked by".

The point of sale now recognizes barcodes assigned to product packages, not just individual products. This helps cashiers quickly sell multi-item packs with the correct quantity, reducing manual entry and checkout mistakes.

[IMP] point_of_sale: Enable scanning of barcode packaging
Actually we can't gie more one barcode for a product
In inventory we can make "package" with various quantity

So with this commit we add the possibility to add a package
of product (1-n) with a specific barcode

Invoice search filters were renamed and adjusted so users can more easily find unpaid, paid, and overdue invoices. The journal dashboard now treats only invoices or bills past their due date as late, avoiding items due today being shown as late.

Modify search filters on the invoice views:
Open -> Unpaid
Closed -> Paid (exclude reversed)
Overdue -> Overdue

Fix journal kanban view "late invoices/bills" should not include due date = today
