fix(ios): fix Fleet Engine location reporting on iOS

Fixes two critical iOS bugs preventing Fleet Engine location reporting:

1. Fixed module export names to match JavaScript expectations
   - Changed RCTDeliveryDriverModule -> DeliveryDriverModule
   - Changed RCTRideSharingModule -> RideSharingModule
   - JavaScript code expects NativeModules.DeliveryDriverModule, not RCTDeliveryDriverModule

2. Fixed event dispatcher initialization to enable event emission
   - Added startObserving() call after allocating DriverEventDispatcher
   - Without this, hasListeners remained false and all events were silently dropped
   - Affects didSucceedVehicleUpdate and didFailVehicleUpdate events

These changes enable proper location reporting to Fleet Engine on iOS,
achieving parity with the Android implementation.

Fixes #70
