Adds canonical: cdn to css/javascript entries in 20_services.yml so that
role-based reverse lookup (web-svc-cdn → cdn) is deterministic. Updates
_build_role_to_key to use the canonical field. Adds an integration test
verifying bidirectional resolution and a lint test enforcing canonical
consistency rules (exactly one primary, no chaining, matching roles).

Eliminates scope-dependent CDN variable bugs by introducing a `cdn` lookup
plugin that resolves paths and URLs at call-time using an explicit application_id
argument. Deletes the old cdn_paths.py and cdn_urls.py filter plugins and their
tests; adds a new unit test for the lookup plugin's _cdn_paths and _to_url_tree
helpers.

Introduces a SPOT for all frontend service loading in sys-front-inj-all/tasks/01_services.yml,
driven by a new generic `service` lookup plugin that resolves services by key or role name
and returns {id, role, enabled, shared, needed}. Needed = enabled AND shared (direct or
transitive). The canonical key→role mapping moves to group_vars/all/20_services.yml
(previously scattered hardcoded rules). Removes per-role service loads from bigbluebutton,
nextcloud, and dashboard. Renames 01_dependencies.yml→01_services.yml and
08_services.yml→08_daemons.yml. Adds flush_handlers after each service load.
