feat(admin): rebuild the restrictions tab on the reference ban modal

Replace the self-invented CRUD (warn/mute/suspend/ban + scope selector)
with the reference-theme ban model: ban method (blackroom suspend /
login ban), duration radios (1/7/14/30/100 days or permanent, default 7),
preset reason chips with an other-reason input, ban note, delete-all-
content switch (posts/comments to trash), and a no-appeal switch with a
required notice that also gates the frontend appeal entry. Banned users
render the status info view (status/start/end/reason) with an unban
leave-a-message form; the record list uses the reference columns and
per-user unban links. Bans notify the user in-site like the reference
zib_updata_user_ban_msg.
