Fix P1 blockers: configurable port, connection leak, race condition, DB path + WAL

Browse Source 
- P1 #551: Add STATUS_PORT env var (default 9191) for configurable HTTP status server port
- P1 #552: Fix SQLite connection leak — wrap all sqlite3.connect() with try/finally in lookup_person(), seed_persons_from_db(), log_signal(), log_presence_change()
- P1 #553: Fix race condition in update_person_state() — compute certainty snapshot under devices_lock, determine state transition under persons_lock, send alert outside locks to prevent stale snapshot
- P2 #559 (included): Add WAL mode + pragmas to init_db() for concurrent write safety
- Database path: Align to /opt/sensor/presence.db in both daemon and install.sh
- Increase connection timeout from 1s to 10s across all functions
- install.sh: Document PRESENCE_STATUS_PORT and PRESENCE_MATRIX_WEBHOOK env vars
