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
