feat: complete XMPP bridge implementation with configuration fixes

- Fix configuration loading by matching JSON field names with plugin manifest keys
- Move configuration to separate package to resolve type conflicts
- Implement bridge startup logic that initializes on OnActivate and updates on OnConfigurationChange
- Add certificate verification skip option for development/testing environments
- Create XMPP client initialization helper function to avoid code duplication
- Add SetOnlinePresence() method to XMPP client for presence management
- Set bridge user online presence automatically upon successful XMPP connection
- Remove unused mock generation and test files as requested
- Update bridge constructor to accept configuration parameter
- Implement proper bridge lifecycle management with Start/Stop methods

The bridge now properly loads configuration from admin console, creates XMPP connections
with appropriate TLS settings, and manages online presence for the bridge user.
