Optimize post-login sequence to load relays before other data

Prioritizes fetching the user's relay list (NIP-65) immediately after login, ensuring that subsequent data fetches (profile, contact list, DMs, feed) utilize the user's preferred relays instead of default ones. This prevents "slow" or incomplete data loading issues caused by relying on defaults.

- Refactored `authService.applyPostLoginState` to sequence relay loading before profile/block loading.
- Refactored `app.handleAuthLogin` to await relay loading before initiating dependent fetches (Hashtags, Moderation, DMs, NWC, Lists, Feed).
- Updated unit tests in `tests/auth-service.test.mjs` to verify sequential execution and correct return values.
