Standardize code formatting across all 173 Rust source files
using rustfmt. No functional changes - purely cosmetic.
This establishes a consistent code style baseline for the
project going forward.
- 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
