Replace token-based CSRF with Sec-Fetch-Site header protection (#2689)
- New CSRF protection middleware inspired by Go 1.25 and research by Filippo Valsorda - https://words.filippo.io/csrf/ - this replaces the old CSRF token based protection.
- Removes all instances of `<input type="hidden" name="csrftoken" value="{{ csrftoken() }}">` in the templates - they are no longer needed.
- Removes the `def skip_csrf(datasette, scope):` plugin hook defined in `datasette/hookspecs.py` and its documentation and tests.
- Updated CSRF protection documentation to describe the new approach.
- Upgrade guide now describes the CSRF change.
