add-in: auto-open taskpane phase 1 + final save after versioning + tracking id = fid

- manifest: TaskpaneId -> Office.AutoShowTaskpaneWithDocument (auto-open marker), bump 1.0.0.4
- metadataService.enableAutoOpenTaskpane: tag doc setting (idempotent, best-effort) called from detect() after sign-in
- versionFlow: final saveDocumentVerified at end of both versioning flows (bug: stamped docx never persisted -> reopen showed untracked)
- tracking id now uses ticket fid (TRACKING_ID_SOURCE="fid", rollback by switching to "guid"), resolveTrackingId + authService.getCurrentFid
- WordAddinGate: restore history.pushState/replaceState that office.js nullifies in taskpane (fixes Next App Router crash)
