Marc-André Bombeck d2f47e3bb5 fix(auth): the refusal code joins the published catalogue ...

Two structural guards caught the new gate. The error-code catalogue is derived
from the route tree on every run and fails in both directions, so a code the
server emits and does not publish is a client that cannot branch on it; the
session-surface guard freezes the short list of files under `src/app` that
resolve a caller without `requireAuth`, and the register route now belongs on
it — `requireAuth` is the wrong gate there twice over, since it would throw at
the anonymous caller the route exists for and this route wants the ABSENCE of a
session.

The code is `auth.already_authenticated` rather than the bare
`already_authenticated`: the catalogue's own header rules that new codes are
dot.case, and it sits beside `auth.mfa.code_invalid` in the same family. The
OpenAPI document renders the catalogue into the ErrorEnvelope description, so
it is regenerated.
