feat(imap): resilient batched sync, stale-session cleanup, and live progress UI

- Add SyncFull trigger and configurable IMAP socket read timeout
  - Replace streaming UID FETCH with UID SEARCH ALL + batched fetch so per-message progress stays responsive and throttling servers can retry with reconnection
  - Finalize stale Running sessions on startup so interrupted syncs no longer show a phantom "syncing" state
  - Show a live syncing pill on the account row; add elapsed time, current folder, and slow-server warning styling in the dialog
