Submit and contact-detail forms now use a plain text input for the QSO
timestamp with a "YYYY-MM-DD HH:MM" placeholder and regex pattern. The
native datetime-local input ignores lang="en-GB" on macOS/iOS when the
system clock is 12-hour, so it was rendering AM/PM against the user's
wishes. Ecto's :utc_datetime cast already accepts this format (verified
space+seconds, T+seconds, and both with and without seconds/Z).
Contact edit workflow grows a third branch: admins still apply directly,
non-owners still go through the admin review queue, and now logged-in
owners of a contact (user_id == current_user.id) can apply edits
directly too. New helpers Radio.owner?/2 and Radio.apply_owner_edit/3
reuse the existing normalize + diff + apply_edit_to_contact path so the
grid-change → enrichment re-enqueue pipeline kicks in automatically.
Anonymous contacts (user_id nil) and other users' contacts both return
{:error, :not_owner}.
Nine new tests cover owner?/2 and apply_owner_edit/3 including the
no-changes, wrong-user, and anonymous-contact paths.
