Route all remaining fill paths through the shared atomic queue
Completes the overfill-race fix (item #1). New queue.php functions, all under the same GET_LOCK + transaction and self-healing numplayers: - pqs_add_player_to_mission (staff 'new' -> registration.php) - pqs_add_player_to_missions (staff 'add to N missions' -> registration.php) - pqs_enqueue_group (kiosk group leader -> callsign.php) - pqs_claim_group_slot (kiosk group member -> callsign.php) callsign.php and registration.php now call these instead of their own non-atomic read-check-insert blocks. Verified on the local stack: scenario test (leader/member/staff paths) and 120 mixed concurrent solo+group writers x3 -> zero overfill, zero drift; HTTP smoke of leader/member/new paths all seat correctly.
