web-svc-logout: merge logout domains into CSP connect-src and refactor task flow

• Add tasks/01_core.yml to set applications[application_id].server.csp.whitelist['connect-src'] = LOGOUT_CONNECT_SRC_NEW.

• Switch tasks/main.yml to include 01_core.yml (run-once guard preserved).

• Update templates/env.j2 to emit LOGOUT_DOMAINS as a comma-separated list.

• Rework vars/main.yml: compute LOGOUT_DOMAINS, derive LOGOUT_ORIGINS with WEB_PROTOCOL, read connect-src via the get_app_conf filter, and merge/dedupe (unique).

Rationale: ensure CSP allows cross-domain logout requests for all configured services.
