frontend: enhance participant token management and update related services

- Renamed `setParticipantToken` to `setParticipantTokenAndUpdateContext` in ContextService to clarify its functionality.
- Introduced ParticipantTokenService to encapsulate token generation logic and manage role/permissions extraction.
- Updated VideoRoomComponent to utilize the new ParticipantTokenService for generating participant tokens.
- Refactored access room method to improve form validation and participant name initialization.
- Added unit tests for ParticipantTokenService to ensure proper functionality.
- Updated sidenav model comments for clarity.
