fix(settings): fix 404 on /settings for root user on cloud instance

- Make Server property nullable in Settings components (Index, Advanced, Updates)
- Add conditional server loading: only load when not on cloud
- Add null checks before using server for DNS validation and proxy configuration
- Fix isInstanceAdmin() to check root team's pivot role directly instead of current team
- Make root team (id=0) bypass subscription check on cloud
- Remove isInstanceAdmin() from main middleware bypass: only settings/admin routes are exempted
- Update isSubscribed() to only check isSubscriptionActive() for navbar consistency
