Story Crater Bot 5ce0b92186 feat(data): add CNPG managed roles + Database CRs for authentik/temporal — replaces missing helmfile post-sync user creation
authentik/temporal DB users+databases were never provisioned (old helmfile hook
gone; db-init-job only made schemas in shared app DB). Adds managed.roles
(authentik/temporal login roles, passwords from basic-auth secrets) + Database CRs
(dedicated DBs owned by each role). Role secrets applied out-of-band (SOPS), not in
kustomize resources so data-schemas app doesn't choke on ciphertext.
