USB kiosk: take and return a drive without a ShopDB login

The people who actually take USB drives are standing at the cabinet, and most
of them have no account here. Check-out and check-in were gated behind a login
that was not doing much anyway: both modes already attribute the action to a
scanned BADGE rather than to the signed-in user, so the login was gating the
screen, not the record.

/usb-kiosk is a full-screen touch page modelled on the parts kiosk, off unless
a site sets usb_kiosk_enabled - every route 404s until then, rather than 403,
so a disabled kiosk does not advertise that there is a door here. It works
against the self-hosted tables or an existing cmmc_usb database.

THE LIST IS THE TRADE. These drives carry no barcode, so unlike the parts kiosk
there is nothing to present and the screen has to offer a list - which exposes
more than a scan-first design, where you had to already hold a drive to learn
anything. So the list is not anonymous: an SSO comes first and must resolve to
a real person before any drive is named, which is the same bar taking a drive
already had to clear. It is a POST so the badge stays out of proxy access logs.
The main screen shows the caller's own drives, what is free, and a COUNT of
everything else; holders of other people's drives appear only behind a second
deliberate tap, so nobody reads the whole cabinet off a wall panel in passing.

A badge that resolves to no employee is REFUSED, unlike the signed-in route
which creates the user row. A checkout nobody can trace to a person defeats the
tracking, and at a kiosk there is no operator standing there to vouch for it.

Returning somebody else's drive asks first and then records the badge that was
SCANNED, so the log says who actually handed it back. That is the honest record
and it needs no change to a schema this app does not own. Refusing a mismatch
outright is a setting but not the default: a drive left behind by somebody on
leave would otherwise be unreturnable at the kiosk, which just moves the problem
to a person with a login.

The authz sweep caught these writes, twice - once for the two mutations and
again for the two list endpoints. Both are exempted with the reasoning written
out beside the parts-kiosk entry rather than silenced. The list endpoints are
POSTs that change nothing.

Verified by driving the real page: SSO on the keypad, tap Take, database moves.

"""The USB kiosk: an UNAUTHENTICATED write, so the guards are the feature.
The kiosk exists so somebody at the drive cabinet - with no ShopDB login - can
take a drive and put it back, with the action attributed to their badge instead
of to a signed-in operator. Everything here is about the bar that opens the door
only as far as it has to: it can move a device between checked-out and
checked-in and nothing else, it refuses a badge it cannot put a name to, and it
does not exist at all until a site turns it on.
Self-hosted mode. The external cmmc_usb path is the same contract against raw
SQL and needs that database to exercise.
