fix(init): resolve startup error message timing issue

Fix race condition where 'please check network or server address' error
was shown on first startup even when API was properly configured.

- Add isLoadingServerConfig state to track server config fetch status
- Modify authStore to wait for server config loading before showing errors
- Ensure loadSettings completes fully before triggering login checks
- Only show network error when config fetch actually fails, not during loading
