Pull request overview

This PR modernizes the CI/CD infrastructure by migrating from traditional pip-based workflows to UV-based GitHub Actions, and consolidates linting tools from multiple separate tools (black, flake8, isort, pydocstyle, bandit) into Ruff.

Key changes:

• Migrated GitHub Actions workflows to use UV for faster dependency management and builds
• Replaced multiple Python linting tools with Ruff (configured in pyproject.toml)
• Added pre-commit configuration for automated code quality checks
• Reformatted code according to Ruff standards (f-strings, quote styles, formatting)

Missing Django version specification for the selenium job. The pytest job on line 74 includes --with django~=${{ matrix.django-version }}.0 but the selenium job on line 101 is missing this specification. This could lead to inconsistent test environments between the two jobs.

The checkout action version is inconsistent. Line 61 uses actions/checkout@v5 while line 11 uses actions/checkout@v6. Both instances should use the same version for consistency.
