test: Add 18 tests for workflows/test_gen/config.py (Module 30)

Coverage boost for test generation configuration (88 lines).

Tests added:
- DEFAULT_SKIP_PATTERNS constant (7 tests: type, not empty, specific patterns)
- TEST_GEN_STEPS constant (11 tests: type, all 4 steps, tier hints, max_tokens)

All tests passing: 18/18 ✓ (first try!)

Module 30 of coverage enhancement initiative.
