NK-WP-0054-T05 phase 2b: each directory consumer binds with its own account
Custody gains LLDAP_SVC_{AUTHELIA,KEYCAPE,PRIVACYIDEA,PROVISIONER}_PASS and
LLDAP_LDAP_USER_PASS becomes ld-admin's. Authelia, KeyCape, the privacyIDEA
resolver and identity-provisioner (new Secret identity-provisioner-ldap) switch
to svc-* accounts; LLDAP's configured super-admin is ld-admin. The LLDAP image
pin waits for the running digest.

# creds-rotate.sh — guided or non-interactive rotation for a single net-kingdom credential.
#
# Usage:
# SECRET=<name> bash sso-mfa/bootstrap/creds-rotate.sh [secrets-dir]
# make creds-rotate SECRET=<name>
#
# # Agent / non-interactive mode (NK-WP-0005):
# SECRET=<name> bash sso-mfa/bootstrap/creds-rotate.sh --non-interactive [secrets-dir]
#
# The script:
# 1. Validates the secret name
# 2. Prints rotation impact and required coordination steps
# 3. Generates a new value (same entropy as original)
# 4. Guides through the atomic update sequence (interactive) or runs it
# automatically (--non-interactive)
# 5. After completion, updates creds-state.yaml
