Improve the user experience in the file browser list view by allowing users to click anywhere on a file card to open it, rather than just the specific link.
- Add a click event listener to the file browser to handle navigation when clicking a card in list view.
- Ensure interactive elements (like buttons or inputs) inside the card do not trigger the card-wide click.
- Add `cursor: pointer` to list view file cards to indicate they are clickable.
- Update retro theme CSS to style the entire card on hover and focus.
- Limit the number of initially visible reactions per file to 2 and calculate the overflow count on the backend.
- Redesign the retro theme CSS to mimic a classic Windows 98 Explorer window, including title bars, toolbars, and sunken panes.
- Add local storage persistence for the file browser view preference (list vs. thumbnails).
Modify the authentication handler to return an unauthorized error when
an invalid or disabled bearer token is provided, rather than silently
falling back to an anonymous request.
This ensures that clients attempting to authenticate but failing (due to
expired, malformed, or disabled tokens) are explicitly notified of the
auth failure instead of proceeding anonymously. True anonymous requests
without any Authorization header remain supported.
