MPT-16776: improve Dockerfile, Makefile, README and compose.yaml (#13)

<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
Closes [MPT-16776](https://softwareone.atlassian.net/browse/MPT-16776)

- README.md: Updated documentation for make targets — `make check-all`
description changed to "run checks and tests" (removed mention of
formatting).
- Makefile: Clarified help text for `make check-all`; updated `test`
target to pass a default "." to pytest when no args are provided (uses
$(if $(args),$(args),.)).
- compose.yaml: Removed explicit `container_name: mpt_tool` from the
`app` service so Docker Compose will auto-generate container names.
- Dockerfile: Base stage now copies `README.md` alongside
`pyproject.toml` and `uv.lock`; minor whitespace/ordering adjustments in
build-stage COPY/RUN steps.
