feat: Improve VFS handling and authentication middleware

- Remove unnecessary debug print statements in VFS and WebDAV
  middleware for cleaner code.
- Fix a bug in `OurDBVFS.exists` to correctly handle root and
  current directory paths.
- Enhance `OurDBVFS.get_entry` to handle '.' path correctly.
- Improve WebDAV authentication middleware to gracefully handle
  unauthenticated requests.
