perf(friendica): single-pass patch for DB creds + system.url; align env URL; tidy vars

- Patch local.config.php in one sed exec:
  * hostname, database, username, password
  * system.url via '#' delimiter to avoid URL slash escaping
  * Single notify: docker compose up
- env.j2:
  * FRIENDICA_URL now uses domains|get_url(application_id, WEB_PROTOCOL)
  * Simplify FRIENDICA_DEBUGGING with |lower
  * Normalize spacing for readability
- vars/main.yml:
  * Minor cleanups (comment header, spacing)
  * Consistent friendica_docker_ldap_config path construction

Why: fewer container execs ⇒ faster runs; idempotent key updates; consistent URL configuration across env and PHP config.
Risk: requires WEB_PROTOCOL and domains|get_url to be defined in inventory/vars as elsewhere in the project.
