room seat cron backstop: expire_lapsed_room_seats sweeps idle mid-game tables — TDD

Phase 6 (final) of the room GATE VIEW + seat-renewal sprint. Cron
backstop mirroring delete_stale_my_sea_draws — the lazy
_expire_lapsed_seats already frees seats on every room/gate-view access,
but a mid-game table nobody reopens past the grace window would keep its
stuck seats forever. This command runs the same sweep over every room
holding a timestamped FILLED slot. No flags; idempotent.

Tests: ExpireLapsedRoomSeatsCommandTest (2) — frees a >2S lapsed seat +
flags RENEWAL_DUE; no-op within grace. Full project suite 1590 ITs/UTs
green.
