Tighten the utils namespace so each subpackage owns one concern:
- utils/applications/* moves under utils/roles/applications/* (helpers
that operate on the runtime applications dict and meta/services.yml).
- utils/service_registry.py and utils/database_service.py move under
utils/roles/applications/services/ as registry.py and database.py.
- utils/entity_name_utils.py becomes utils/roles/entity_name.py.
- utils/invokable.py, utils/valid_deploy_id.py, and the existing
utils/roles/resource_validation.py group under utils/roles/validation/
as invokable.py, deploy_id.py, and resources.py.
- utils/templating.py and utils/jinja_strict.py split into
utils/templating/ansible.py (Templar + TrustedAsTemplate, lookup-env
shortcut) and utils/templating/jinja.py (vanilla Jinja2 Environment,
multi-pass strict render).
Every caller in utils, cli, plugins, roles/<role>/{filter,lookup}_plugins,
tests, and the docs that link to the moved files is updated to the new
import paths. Test files mirror the new source layout
(tests/unit/utils/{roles,templating}/...).
New READMEs at utils/cleanup/, utils/roles/, utils/roles/applications/services/,
utils/roles/validation/, and utils/templating/ follow the
documentation.md and readme_md.md guidelines.

Return a sorted list of communication-channel app IDs that are deployed on

Deployment check : app ID must appear in group_names.

Channel check : app must declare services.prometheus.communication.channel: true
