fix: resolve file management operations not working (#83)

- Fix rename: context menu was nullifying target reference before rename dialog could use it
- Fix delete files/folders: auth extractors were mandatory, causing 401 when auth not configured
- Fix view-file: async fetch race condition with context menu cleanup
- Fix orphaned ID mappings on file deletion
- Fix Authorization: Bearer null headers sent without token
- Add OptionalUserId and OptionalAuthUser infallible extractors
