Both reserve and unreserve go through ActionButton now (reason -> dry-run ->
confirm, journalled) like every other admin action. The reserve modal keeps
just the username field and hands off; it autofocuses and echoes @<name> live
so the field being filled is unambiguous.
The reserve modal delegated to a nested ActionButton, whose own flow modal
opened over it - the username field ended up behind it and the request preview
came through empty on confirm. Replace it with a modal that owns its username
and reason fields and posts the reserve/unreserve command directly. Render the
@ prefix as text, not an icon.
Move "Reserve username" into a modal opened from the page actions, and keep a
single search toolbar in the query panel, so the page matches Collectible
Usernames instead of stacking two toolbars with an unconstrained input.
A plain blocklist for names like @support - separate from the collectible
system, so a reservation has no owner, no price and no "bought on Fragment"
badge.
- reserved_usernames table + migration.
- Enforced in replacePeerUsernameTx (the single editable-username write point:
account.updateUsername, channels.updateUsername, @BotFather /setusername) and
in the collectible mint path; a reserved name returns USERNAME_OCCUPIED.
- admin.Service: ReserveUsername / UnreserveUsername (journalled commands) and
the ReservedUsernames listing.
- adminapi: /v1/reserved-usernames{,/reserve,/unreserve}.
- telesrv-admin panel + a "Reserved Usernames" page in the web UI (dist rebuilt).
- Postgres and in-memory store implementations; the memory registry gains an
optional reserved-name check so tests exercise the same rule.
The "*" wildcard was never in assignablePermissions, so an operator holding it
(the one the first-run wizard creates) showed every box unticked while having
every right, and there was no way to take it away. Its own row fixes both; the
grid is disabled while it is on, since normalisePermissions collapses "*" plus
anything back to "*".
That made guardManagerRemoval reachable from the UI for the first time, so it
now has an integration test covering the wildcard match and the enabled filter
in its SQL.
