The admin settings screen auto-set the browser zone whenever it loaded an
empty timezone, guarded only by a per-mount ref. After an admin cleared the
timezone (empty = API-host-local), the next open re-fetched "" and
auto-set the browser zone again, so the empty choice could not persist.
Add a twelfth settings field, timezone_configured (strict bool, default
false), carried by the core settings table, the stored JSON document and
the admin GET/PATCH. The screen now auto-sets only when the timezone is
empty AND timezone_configured is false, patching the flag with the
detected zone; saving the timezone field (including clearing it) also
sends timezone_configured: true. Detection returning nothing sets nothing.
