chore(keycloak): switch to KC_BOOTSTRAP_* admin vars and update compose/templates (#166)

Fixes: #165

- Replace deprecated KEYCLOAK_ADMIN / KEYCLOAK_ADMIN_PASSWORD with
  KC_BOOTSTRAP_ADMIN_USERNAME / KC_BOOTSTRAP_ADMIN_PASSWORD.
- Update compose files to pass new env vars to the Keycloak container.
- Refresh .env templates to reflect the new names.
- Remove references to deprecated vars.

Touched:
- compose/.env-with-keycloak-template
- compose/keycloak/.env-template
- compose/keycloak/compose-keycloak.yaml
- compose/keycloak/compose-keycloak-no-nginx.yaml

Why: eliminates KC-SERVICES0110 warnings and ensures deterministic, persistent admin on first bootstrap.

BREAKING CHANGE: set KC_BOOTSTRAP_ADMIN_USERNAME and KC_BOOTSTRAP_ADMIN_PASSWORD instead of KEYCLOAK_ADMIN*.
