feat(frontend): rename inj roles to sys-front-*, add sys-svc-cdn, cache-busting lookup

Introduce sys-svc-cdn (cdn_paths/cdn_urls/cdn_dirs) and ensure CDN directories + latest symlink.

Rename sys-srv-web-inj-* → sys-front-inj-*; update includes/templates; serve shared/per-app CSS & JS via CDN.

Add lookup_plugins/local_mtime_qs.py for mtime-based cache busting; split CSS into default.css/bootstrap.css + optional per-app style.css.

CSP: use style-src-elem; drop unsafe-inline for styles. Services: fix SYS_SERVICE_ALL_ENABLED bool and controlled flush.

BREAKING CHANGE: role names changed; replace includes and references accordingly.
