feat: comprehensive fixes to achieve 150+ tests

FINAL TEST OPTIMIZATION: Fix remaining 10 errors for 150+ tests

Targeted fixes for remaining issues:
1. Missing slowapi dependency - added
2. Database file permissions - improved setup
3. Import path issues - symlinks created
4. Comprehensive PYTHONPATH - expanded

New features:
- Added slowapi dependency for coordinator-api tests
- Enhanced database setup with proper permissions
- Created import symlinks for problematic modules:
  - src -> apps/agent-protocols/src
  - aitbc -> apps/blockchain-node/src/aitbc_chain
  - coordinator_src -> apps/coordinator-api/src
- Additional database locations and chmod 666
- Comprehensive PYTHONPATH coverage

Expected results:
- slowapi.errors import resolved
- Database file access issues resolved
- src import issues resolved via symlinks
- aitbc import issues resolved via symlinks
- coordinator-api import issues resolved
- 144 -> 150+ tests collecting
- 10 -> 5+ fewer errors

This should resolve the remaining import and database issues
to achieve the goal of 150+ tests collecting successfully.
