feat(save-attachments): editable filenames, Hebrew status, smoother subfolder load

- DataGrid case picker now shows status via CaseStatusToHebrewConverter
  (added PendingHearing / PendingDecision mappings)
- Attachment row replaces the read-only filename TextBlock with a TwoWay
  TextBox so users can rename a file before saving (flows through
  EspoAttachment.Name into the upload + the on-disk path)
- SaveAttachmentsViewModel.IsLoadingSubfolders gates the folder ComboBox
  while EnsureCaseSubfolders / GetCase / ListNetworkStorageFolder run,
  so users can't pick a stale "(שורש התיק)" before the real list arrives
- About tab: ResolveDisplayVersion now reads from the host VSTO assembly
  (*.OutlookAddin) instead of the UI assembly. The UI csproj is SDK-style
  with no <Version> so it always reported 1.0.0.0, which leaked into the
  About line on dev installs
- Bump to 1.1.2.0 (csproj + AssemblyInfo) to match the v1.1.2 tag that
  will trigger the Gitea Actions auto-publish to platform.dev
