UV Package Manager Integration

[oyurekten]

[commit d26af14]

• migration from poetry to UV tool - removed all other configurations (setup.py, requirements.txt, etc.)
• ruff lint and formatting tool with common rules.
• lint-import tool integration. Identify unexpected imports in isatools modules. For example, flask and sqlalchemy packages will be used only in isatools.database package. Rule contracts are in pyproject.toml.
• pre-commit tool: It checks lint and format related rules before commits. configuration file is .pre-commit-config.yaml
• github CICD pipeline is updated. It uses uv tool
• README file is updated to explain new development environment
• FIX: fix common lint errors
• SKIPPED TEST: Unit test test_info_reporting_bii_i_1_with_study_groups_comment_isatab is skipped. After fixing linting errors, the method under test returns configuration errors. Test input data and/or expected value should be reviewed and the unit test should be updated.
