This update removes an outdated testing workaround now that key web client areas have moved to the newer framework. It helps keep automated tests simpler and more accurate, with no expected change for end users.

Now that most of the webclient codebase (fields, views, client actions...) has been converted to owl, the legacy extra next tick used in a lot of tests is no longer necessary. This commit removes the helper and its usage. At some places, a real tick was needed, but we didn't see it because of the use of the legacy extra next tick.

Several Odoo screens were cleaned up by removing an old setting that is now handled automatically by the platform. This reduces maintenance complexity without changing how users interact with the affected forms.

This option is no longer necessary since [1] as the value is now reloaded by default.

This update replaces an older translation helper with the current standard one across several Odoo Enterprise apps. It is an internal cleanup that keeps labels and messages translated consistently without changing day-to-day functionality for users.

In a previous commit 8bfa76a, _lt() returns _t().
So, in this commit, all usages of _lt() are replaced by _t().
