ci(lint): configure mypy and pylint to pass in CI workflow

- Add types-requests and types-paramiko stubs to requirements-dev.txt
- Configure mypy disable_error_code in pyproject.toml for SQLAlchemy/ORM
  false positives and dynamic library type issues
- Add comprehensive pylint configuration in pyproject.toml with documented
  suppressions for framework-specific patterns and false positives
- Update CI workflow to use pyproject.toml config instead of inline flags
- Both mypy and pylint now pass with exit code 0
