Problem: closing and reopening the translate job page (or tab close+reopen)
lost the progress bar because the in-memory store starts fresh. The backend
keeps translating, but the UI shows no progress.
Fix:
- Store: save {runId, jobId, isFullRun} to sessionStorage on startTranslationRun()
via _saveToSessionStorage()
- Store: add reconnectToRun() — re-establishes WS without resetting store state,
preserving any progress data already received
- Store: add getStoredActiveRun() — public reader for sessionStorage
- Store: clear sessionStorage via _clearSessionStorage() on terminal states
(added to _cleanup() called by WS terminal, max-reconnects, stop, reset)
- Page: add that checks getStoredActiveRun() after job loads
and calls reconnectToRun() to pick up the live progress
Edge cases handled:
- Store already connected to same run → skip (no duplicate WS)
- sessionStorage unavailable → silent catch
- SPA navigation → store already has the run, WS still connected → skip
- Page reload → sessionStorage has the run, reconnects
- Tab close + reopen → same as reload
- Run completes while away → sessionStorage cleared by _cleanup()
- Run already finished → getStoredActiveRun() returns null → skip
