fix: pass enhance_level instead of removed enhance_with_ai/ai_mode to analyze_codebase (#323)

Two call sites (_run_c3_analysis in unified_scraper.py and _analyze_c3x in
unified_codebase_analyzer.py) still passed the old enhance_with_ai and ai_mode
kwargs which were replaced by enhance_level. This caused a TypeError when
running C3.x codebase analysis.
