Merge origin/master into feat/apple-typed-resources-and-fixes

Brings in custom relays, relay connection policies, storage cache clearing, and
receiver-failure reporting. Apple-side conflict resolutions:
- CoreRepository: keep CoreDispatcher, adopt master's relay factory + network
  transition guard, drop the now-unused serial queue.
- TransferDetailsView: keep the toolbar-share layout; adopt master's
  invitationPresentation-based QR panel and the new .failed receiver case (typed).
- SettingsModel/SettingsScreen: typed L10n titleKey with master's .network case;
  relay controls and the Free up space / storage redesign coexist.
- Add the missing transfer_receiver_failed localization key.
- Regenerate l10n from the merged strings.json; keep the Apple catalog untracked.
- Drop the notificationsEnabled test assertion (notifications preference was
  intentionally removed on this branch).
