refactor(HomeView): remove unused methods and deduplicate API server calls

- Remove unused loadSettings() method (functionality moved to initializeIdentity)
- Remove unused checkRegistrationStatus() method (functionality moved to initializeIdentity)
- Deduplicate ensureCorrectApiServer() calls (now only called once in initializeIdentity)
- Clean up import statement formatting for NOTIFY_CONTACT_LOADING_ISSUE

Reduces code complexity by eliminating 66 lines of dead code while maintaining
all existing functionality. Improves maintainability by consolidating initialization
logic into a single method.
