Website Form Require Legal

This module extends the website form builder so you can require visitors to accept legal terms before sending a form.

• In the website editor, when you select a form, a new option "Legal terms acceptance" appears next to the URL setting. Ticking it inserts a checkbox block with the text "Agree to terms and conditions" just above the submit button (or above the captcha if one is present).
• The checkbox is marked as required, so the browser blocks submission while it is unticked.
• The submit button starts disabled whenever the legal terms block is present on the page, and it only becomes clickable once the visitor ticks the checkbox. Unticking it disables the button again.
• The inserted block uses the same label width as the other form fields, so it lines up visually with the rest of the form.

It works on the public website frontend and inside the website builder. No new menus, database models or reports are added; the change is limited to website forms and their submit button behaviour.
