Bernd Worsch 6d25d088d7 feat(sso-mfa): T02/T03 live apply — age-encrypted secrets, CNPG cluster (NK-WP-0001-T02/T03)
- Add encrypt-secrets.sh / decrypt-secrets.sh: age-based secrets workflow
  replaces KeePassXC dependency; encrypted .env.age files committed to repo
- Add bootstrap/secrets.enc/: all component secrets encrypted to age pubkey
- Fix .gitignore: allow secrets.enc/**/*.age while blocking plaintext
- Fix verify-t02.sh: update netpol names for Authelia+LLDAP+KeyCape stack
- Fix verify-t03.sh: remove keycloak_db/role checks; fix ((PASS++)) set-e bug
- Update postgresql/cluster.yaml: drop keycloak_db, bootstrap privacyidea_db only
- Update postgresql/create-secrets.sh: remove keycloak secret
- Fix netpol-databases.yaml: add port 8000 for CNPG instance manager HTTP API
- T02 COMPLETE: namespaces, network policies, cert-manager issuers applied
- T03 COMPLETE: CNPG operator installed, net-kingdom-pg cluster healthy

# decrypt-secrets.sh — decrypt secrets.enc/ to secrets/ using age
#
# Usage:
# ./decrypt-secrets.sh [OUTPUT_DIR] [AGE_KEY_FILE]
#
# OUTPUT_DIR where to write plaintext secrets (default: ./secrets)
# AGE_KEY_FILE age private key file (default: ~/.config/net-kingdom/age.key)
#
# Decrypts all *.age files in secrets.enc/ to OUTPUT_DIR for use by
# create-secrets.sh scripts. Shred OUTPUT_DIR when done:
# find secrets/ -type f -exec shred -u {} \; && rm -rf secrets/
#
# The age key must be present on the machine. Keep it outside the repo:
# ~/.config/net-kingdom/age.key
