fix: resolve 'box in a box' nesting issues in codebase
ISSUES RESOLVED: 1. Coordinator API unnecessary nesting BEFORE: /apps/coordinator-api/aitbc/api/v1/settlement.py AFTER: /apps/coordinator-api/src/app/routers/settlement.py - Moved settlement code to proper router location - Moved logging.py to main app directory - Integrated settlement functionality into main FastAPI app - Removed duplicate /aitbc/ directory 2. AITBC Core package structure ANALYZED: /packages/py/aitbc-core/src/aitbc/ STATUS: ✅ Kept as-is (proper Python packaging) - src/aitbc/ is standard Python package structure - No unnecessary nesting detected - Follows Poetry best practices LEGITIMATE DIRECTORIES (NO CHANGES): - /cli/debian/etc/aitbc (Debian package structure) - /cli/debian/usr/share/aitbc (Debian package structure) - Node modules and virtual environments BENEFITS: - Eliminated duplicate code locations - Integrated settlement functionality into main app - Cleaner coordinator-api structure - Reduced confusion in codebase organization - Maintained proper Python packaging standards VERIFICATION: ✅ No more problematic 'aitbc' directories ✅ All code properly organized ✅ Standard package structures maintained ✅ No functionality lost in refactoring
