[IMP] pms: add active field to board service

[DarioLodeiros]

Summary

Allow archiving board service regimes that are no longer commercialised (seasonal packages, retired group rates, board services that have been replaced) without affecting historical reservations or invoices that reference them.

Mirrors the same pattern recently introduced for room.closure.reason (#xxxx).

Behaviour

The active flag lives on pms.board.service as the source of truth and its write override propagates archive/restore down to:

• pms.board.service.line (composition of the regime)
• pms.board.service.room.type (per-room-type assignment)
• pms.board.service.room.type.line (composition at room-type level)

Each model also exposes its own active field so individual rows can be toggled independently when needed (for example, retire a regime only for a specific room type).

Historical pms.reservation.board_service_room_id references remain intact since the rows are archived rather than deleted; the regime simply stops appearing in selection dropdowns for new operations.

UI

• pms.board.service and pms.board.service.room.type forms gain the standard "Archived" ribbon.
• pms.board.service form has a dedicated search view with an "Archived" filter, wired to the configuration menu action.

Test plan

• Existing board-service tests pass (-i pms --test-tags /pms:TestBoardService).
• New regression test test_archive_board_service_propagates_to_children covers forward and reverse propagation of the active flag.
• Manual: archive a board service from the UI → the ribbon appears, the regime no longer shows up in reservation dropdowns, and the "Archived" filter on the configuration list view brings it back.
