fix(faq): toggle worked server-side but click did nothing — nested forms

Filament pages wrap their content in an outer <form>. My inline
<form method="POST"> for the hint toggle + reset was nested inside
that outer form — invalid HTML, so browsers dropped my submit and
either did nothing or ran the outer Livewire form's handler.

Replaced both forms with plain <button type="button"> + onclick
fetch() POST + window.location.reload(). Controller now also returns
JSON when Accept: application/json (fetch sends that) instead of a
back() redirect.

The server-side flip was always correct — verified via a Feature
test that posts to /app/hints/toggle and asserts the user column
flipped from true → false.
