fix: share dialog not opening + connect to backend API

- Fix showShareDialog: add try-catch, null checks, prevent textContent
  from destroying header icon (use span child instead)
- Capture file/folder target before closeContextMenu to prevent race
- createSharedLink now calls real backend POST /api/shares instead of
  localStorage-only mock (still caches locally for offline compat)
- Fix share_handler.rs: use OptionalAuthUser instead of AuthUser to
  prevent 401 when auth is disabled (same pattern as delete/trash)
- Add null-safety to closeShareDialog
- Reset new-share-section on dialog open
