fix(distribution): revert OIDC enforcement — enabling it gated /healthz probe (service down)

Flipping Auth__Enabled=true gated the /healthz readiness probe (302->NotReady->
no endpoints->distribution.iamworkin.lan down, healthz=000). Classic
feedback_k8s_probes_behind_auth_middleware. Revert to false (OIDC env block kept,
gate off) to restore service. Proper fix (AllowAnonymous /healthz + CA-trust +
idempotent Editions seed + OIDC-challenge wiring + browser-proof) -> falcon OIDC lane.
