feat: Add make test-new for quick test file template creation

- Add test-new make target for generating test file templates
- Interactive prompt for test name with validation
- Generates structured test class with setup/teardown methods
- Includes basic functionality, edge cases, and error handling placeholders
- Follows TDD best practices with Arrange-Act-Assert pattern
- Auto-generates class names from test names (snake_case to PascalCase)

Usage: make test-new
Then enter test name when prompted (e.g., "schema_validation")
