Phase 3c of migration #2: drop the Secret stanza from auth.yaml; the Middleware
stays and references filebrowser-auth-infisical (synced from homelab/prod
/filebrowser). ArgoCD prunes the old plaintext filebrowser-auth secret — the
bcrypt htpasswd leaves git. Completes migration #2.

Phase 3b of migration #2: Middleware.spec.basicAuth.secret now references the
Infisical-managed secret. Secret stanza in auth.yaml left in place as fallback
until 3b is verified (401 w/o creds, 200 w/ creds), then removed in 3c.
