fix(settings): move board access control out of the nested form

The unified board settings form wrapped BoardAccessSettings (which renders
its own <form> via the user/group access forms) inside the outer board
settings <form>. Nested <form> elements are invalid HTML and cause React
hydration to fail (error #418), so the access save button's onSubmit never
runs and clicking 'Save group permission' only reloads the page without
persisting.

Fix: keep the six settings sections in the outer <form>, and render the
Access control and Danger zone sections outside it as siblings. This restores
the independent mutation/forms for access permissions, matching the original
intent of the unified settings form.

Closes #6653
