Fix autofocus on dynamically inserted forms, remove this.blur() handlers

form_controller.connect() now blurs the previously focused element and
explicitly focuses the [autofocus] element when a form is inserted into
the DOM (via Turbo Stream). Only runs when an [autofocus] element is
present, so closing forms and other stream updates are unaffected.

Remove all onclick='this.blur()' inline handlers from templates — they
were a workaround for the same autofocus problem, now solved properly
via the Stimulus lifecycle.
