refactor(communities): remove DID generator dependency from service layer

Update CommunityService and server initialization to remove Coves-side
DID generation. V2.0 architecture delegates all DID and key management
to the PDS for simplicity and faster shipping.

Service Layer Changes:
- Remove didGenerator parameter from NewCommunityService
- PDS provisioner handles account creation and receives DID from PDS
- Simplified service constructor signature

Server Initialization Changes:
- Remove DID generator initialization
- Simplify PDS provisioner creation (no userService needed)
- Add comprehensive logging for dev vs production modes
- Unify PLC directory URL configuration for identity resolver
- Ensure dev mode uses local PLC directory for E2E testing

Configuration:
- IS_DEV_ENV=true: Use local PLC directory for both creation and resolution
- IS_DEV_ENV=false: Use production PLC or IDENTITY_PLC_URL override

This change prepares for V2.0 where communities are fully PDS-native entities.
