This update replaces several custom styling helpers with standard Bootstrap alternatives across multiple Odoo apps. It helps keep the interface more consistent and easier to maintain, with little expected change for end users.

Refine and adapt BS default utility classes.

This fix makes several automated product walkthroughs finish in a clean, stable state instead of stopping while a form is still being edited. It improves test reliability across accounting, barcode, rental, signing, knowledge, and other areas, reducing false failures and helping teams ship changes with more confidence.

Cf odoo/odoo#96517

This update removes redundant checks that caused extra background work without changing what users see. It should make affected operations slightly more efficient and reduce avoidable system load.

Making a `exists()` on a record got by a `search()` is useless and
lead to a extra useless query. Remove them.
