web: Simplify web configuration and token management

- Remove telemetry functionality and related UI elements
- Add automatic token generation using UUID
- Remove manual token verification process
- Sync Citron username with profile username automatically
- Simplify web configuration UI and improve error messages
- Update host room error message for clarity

This change streamlines the web service configuration by removing
unnecessary complexity and automating token management. Users no longer
need to manually verify tokens, and the Citron username is automatically
kept in sync with their profile username.
