The delete button was offered on every invitation regardless of state, and the
query behind it deleted any row it was given. Deleting an unused code takes it
off the list without taking it out of anybody's inbox: the person still holds
something that looks like a valid invitation, it silently stops working, and
there is no longer a record of who it went to or why. Revoke is what stops a
live code — it leaves the row behind, marked.
So the delete is now for spent codes only, in three places rather than one: the
query carries AND used_at IS NOT NULL, the route answers 409 with the reason
instead of pretending the row is missing, and the button is rendered only on a
used row.
A "Clear N used" control alongside, since the complaint was clutter and clearing
them one at a time is not much of an answer. Same rule — nothing unused or
revoked is touched — and it confirms first, because it is still a delete.
The bulk route is declared before /invites/:id, or Express reads "used" as an id.
Verified against the live database: deleting an unused invitation is refused and
the row survives, deleting a used one works, the bulk clear removes only used
ones, and the unused probe row was still there afterwards.

registration_enabled was a single switch: open to anyone, or closed to
everyone. This adds the setting an operator actually wants in between — open
to people you invited.
A code is single-use, expires (7 days by default, 90 maximum), and can be
revoked or deleted. It is stored hashed with only its last four characters
kept, because an invite grants account creation and a database dump should
not hand someone a working one. The code is readable exactly once, in the
response that creates it.
The claim is a single conditional UPDATE carrying every condition, so two
registrations racing the same code cannot both succeed. It happens after the
account exists, so a code is never spent on a failed registration — and if
the race is lost, the just-created account is removed rather than left behind
as a free registration. The rejection never says which of the four reasons
applied; distinguishing them would tell someone probing codes which guesses
were closer.
Codes avoid I, L, O and U so they survive being read aloud or copied off a
screen, and matching ignores case and separators.
The sign-up field appears only when the server says a code is required. The
admin card creates, lists, revokes and deletes, and carries the toggle.
Verified against the live database: create, claim, second claim refused,
unknown code refused, revoking a used code refused, delete. 684 tests pass.
