P1: drivers + trips(★state machine) + matching(Redis GEO) + tariff engine + maps + realtime + seed

- drivers: apply/approve/status/location (+Redis GEO presence)
- trips: request→accept→status transitions + trip_events audit + offers via socket
- matching: Redis GEO nearby drivers
- tariff: JSON-rule engine (time_or_distance/window/rounding) + quote endpoint
- maps: straight-line routing seam (انطلق later)
- realtime: Socket.IO gateway (JWT auth, tenant rooms)
- seed: demo tenant siro + default tariff on boot
- migration InitP1 (drivers/tariffs/trips/trip_events)
