chore: update devcontainer configuration and Dockerfile (#4298)

* Add Dockerfile for devcontainer with Rust and UV setup

* Update devcontainer configuration to use Dockerfile and enhance features

- Switch from using a pre-built image to building from a Dockerfile.
- Replace Poetry feature with Hadolint for linting Dockerfiles.
- Add new VSCode extensions: Ruff, Autodocstring, Indent Rainbow, and Hadolint.
- Set default terminal profile to zsh in VSCode settings.
- Add a postStartCommand to initialize the environment.
- Change remote user to 'vscode'.

* Update test command in VSCode tasks to 'make unit_tests'

* chore: remove unnecessary comment
