Support Docker CLI-style Go templates for docker compose ls and docker compose images while keeping existing table and json output paths available. The formatter contexts expose the fields already shown by those commands and add coverage for custom templates plus json template rendering.

Description
This adds Docker CLI-style Go template formatting to
docker compose lsanddocker compose images.Both commands already had a
--formatflag, but they were still routed through Compose's older table/json formatter path while sibling commands such asdocker compose psuse Docker CLI template formatting. This PR adds typed formatter contexts for Compose project rows and Compose image rows, then routes custom templates through the Docker CLI formatter.The existing
--format jsonbehavior is intentionally preserved as the current Compose JSON array output, to avoid changing that output shape for existing consumers. Template JSON remains available through templates such as--format '{{json .}}'. If maintainers prefer--format jsonto be aligned with the per-row Docker CLI output as part of this feature, I am happy to adjust.Testing
