05eb74022a chore(ci): migrate Python tooling to uv and standardize workflow execution (#7386)
# Description of Changes

This PR modernizes the project's Python tooling across GitHub Actions by
migrating CI workflows from pip-based dependency management to `uv` and
aligning Python execution with the engine project's managed environment.

### What was changed

- Replaced `actions/setup-python` and ad-hoc `pip install` steps with
`astral-sh/setup-uv` across CI workflows.
- Configured shared `uv` dependency caching using
`engine/pyproject.toml` and `engine/uv.lock`.
- Updated Python script execution to use `uv run --project engine
--locked` for a consistent runtime environment.
- Replaced package installation steps with `uv sync` for the required
dependency groups (e.g. `tools` and `cucumber`).
- Added Docker image build validation for both production and
development AI engine images.
- Updated workflow cache configuration and Docker build context where
required.
- Removed obsolete Python requirements files that are no longer needed
after the migration.
- Applied minor Python code modernizations, including import cleanup,
modern built-in generic type annotations (`list[...]`, `tuple[...]`,
`float | None`), and small style improvements.
- Removed unnecessary Python formatter/linter extensions from the
development container configuration.

### Why the change was made

- Standardize Python dependency management across the repository.
- Reduce duplicated dependency installation logic in CI.
- Improve workflow performance through shared dependency caching.
- Ensure all Python utilities execute against the same locked dependency
set managed by the engine project.
- Simplify long-term maintenance by eliminating legacy requirements
files and pip-specific workflow steps.
