This update simplifies how Odoo Mail tracks whether a message needs a user's attention. It reduces unnecessary data sent to the browser, which can improve maintainability and help keep messaging performance efficient without changing the visible user experience.

Before this PR, `_message_format` sends all of the users that had a "need action" on a message to the JS code.
Since https://github.com/odoo/odoo/pull/162065, this behavior is not necessary
anymore and a boolean can be used.

Translation export files now automatically remove duplicate references that do not add useful information. This keeps exported translation files smaller and reduces unnecessary noise in reviews or updates when code is moved.

Code translation references have all their line numbers set to 0 in order to avoid unnecessary diff when moving code around. This leads to situations where two references are exactly the same, adding more lines for no benefit.

This commit adapts the translation export code to properly remove all duplicate entries.

The mail system now sends only whether a message is starred instead of sharing the full list of people who starred it. This reduces unnecessary data transfer and simplifies message handling without changing the visible user experience.

Before this PR, `_message_format` sent all of the users that starred a message to
the JS code.
Since https://github.com/odoo/odoo/pull/162065, this behavior is not necessary
anymore and a boolean can be used.

This update converts internal popover interface tests to Odoo's newer testing framework. It helps maintain reliability of the web interface while making future test maintenance easier, with no direct change expected for end users.
