fix: resolve mypy configuration issues and add comprehensive CI testing

Fixed mypy configuration and syntax issues:
1. mypy.ini configuration:
   - Removed invalid per-module flags from [mypy-src.*] section
   - Per-module sections now only contain valid flags (ignore_missing_imports)
   - Cleaned up systematic duplication throughout configuration file

2. Syntax error fixes:
   - Fixed unterminated string literal in templates.py
   - Improved f-string formatting for better readability

3. Added comprehensive CI testing infrastructure:
   - Created dev-tools/scripts/ci_check.py for local CI testing
   - Script matches GitHub Actions workflow exactly
   - Added Makefile targets: ci-check, ci-check-quick, ci-check-fix, ci-check-verbose
   - Enables catching CI issues locally before pushing

The CI check script validates:
- mypy.ini configuration parsing and per-module flag compliance
- Python version consistency across configuration files
- Python syntax errors in common problem files
- Code formatting (Black, isort)
- Linting (flake8, mypy, pylint)
- Complexity analysis (radon)
- Security checks (bandit, safety)

All configuration and syntax issues resolved. Remaining mypy errors are type annotation issues, not configuration problems.
