P2: ride types + class-aware matching + round-trip + dispatch + wallet + FCM + WS live location/WebRTC

- ride-types: per-tenant catalog (economy/comfort/electric/family_van/women/scooter), seeded
- matching now class-scoped (geo:drivers:{tenant}:{class}); trips match by requested type
- trips: is_round_trip (doubles distance for fare) + payment_method + wallet settlement on paid
- dispatch: operator creates trip for phone customer (role-guarded)
- wallet: balance + credit/debit + txns + self topup; wallet-paid trips settle rider→driver
- notifications: FCM device tokens + best-effort push (assign event)
- realtime: trip:join, live driver:location broadcast, WebRTC call signaling (offer/answer/ice/end)
- migration InitP2 (ride_types, wallets, wallet_txns, device_tokens, trips.is_round_trip)
