fix: refresh profile on lock, reuse tab for footer links

- doLock() re-queries getActiveProfileInfo so the lock screen shows the
  correct active profile after switching
- Lock screen footer links (NostrKey.com, Ts&Cs, Donate) now open in
  the shared nostrkey-options tab instead of spawning new tabs
