[IMP] pms: add active field to room.closure.reason

[DarioLodeiros]

Summary

• Add active Boolean field (default True) to room.closure.reason so reasons that are no longer in use can be archived without losing the link from historical records that already reference them.
• Show the standard "Archived" ribbon on the form when the record is archived.
• Add a dedicated search view with an "Archived" filter and wire it to the configuration menu action.

Motivation

Operations teams cycle through closure reason catalogues fairly often (renaming, splitting categories, etc.). Without active, obsolete reasons stay visible in selection dropdowns forever and the only workaround is to delete them, which is not possible once historical closures reference them.

Test plan

• Existing closure reasons are kept active=True after the module update (default on the new column).
• Form view shows the "Archived" ribbon when toggled off and hides it when active.
• The "Archived" filter under the dedicated menu lists archived reasons.
• Selection dropdowns on pms.reservation / out-of-service flows no longer include archived reasons by default.
