v1.09 — Fix ODT download, selective removal, Display Level Full

- Direct CDN download (officecdn.microsoft.com/pr/wsus/setup.exe) instead of broken fwlink redirect
- HttpClient with proper redirect handling, content-type check, file size validation
- Selective C2R removal: each product listed separately, only checked items removed
- OfficeDetector splits ProductReleaseIds into individual entries
- Display Level="Full" for removal (shows Microsoft progress UI)
- Confirmation dialog before removal on all pages
