View only mode

Add a view-only mode that prevents editing. This is most useful for viewing docs on a site like readthedocs.

Another approach: delegate builds to PreTeXt / Sphinx / etc.

mdBook support might be easy: see https://github.com/dcampbell24/mdbook-djot/blob/main/src/lib.rs, an example of applying the preprocessor to .dj files. But, that doesn't provide support for e-books that PreTeXt would

Thoughts on a view only mode:

1. Add this as a radio button (browse / edit) in the GUI, probably on the same line as the filename.
2. A startup param on the webserver can send the button locked to browse only.
3. If the user toggles from browse to edit, no other actions are needed. To toggle from edit to browse, need to deactivate TinyMCE if it's currently editing.
4. Add checks to the server for security to refuse update messages from the Client in browse mode.
