fix(wordpress): route the outpost OAuth path so the gate is a gate, not a dead end

Verified against the deployed cluster: GET /wp-admin/ correctly 302s to
https://www.renner.uno/outpost.goauthentik.io/start?rd=... — and that URL
returned WordPress's 404 page, because /outpost.goauthentik.io fell through to
the public '/' prefix router.

The effect was that /wp-admin was unreachable rather than protected. An
attacker gains nothing, but neither does the editor the gate exists for.

paperless needs the same route and solves it with a separate Ingress on
auth.renner.uno (apps/authentik/paperless-gate-ingress.yaml). Here the whole
flow stays on www.renner.uno, so the path belongs in this rule set.

These endpoints are the login flow itself and are served by the outpost, so
routing them to it is not an authentication hole.
