feat(peek): support File Explorer Home page items

Fixes #42414

Adds path resolution for items selected from the File Explorer Home page.
The Home page displays recent files and pinned items as shell references,
which need to be resolved to their actual file paths for Peek to preview.

Changes:
- Added HomePagePathResolver helper class
- Detects Home page shell locations
- Resolves shell item references to file paths
