feat: complete codebase remediation with all phases

Phase 1: Security fixes
- Added CORSMiddleware to marketplace-service with specific origins
- Fixed blockchain-node auth to fail closed on JWT errors
- Added security regression tests (test_cors_configuration.py, test_dispute_auth.py)

Phase 2: Repository cleanup
- Removed 51 fix/backup/legacy files
- Deleted marketplace-service-debug directory

Phase 3.1: Python version constraints
- Updated aitbc-crypto and aitbc-sdk with requires-python >=3.13
- Added explicit [tool.poetry].packages declarations

Phase 3.2: Agent service DI architecture
- Created aitbc-agent-core package with protocols and shared service
- Implemented adapters for agent-management and coordinator-api
- Created factory functions for gradual migration
- Added migration comments to existing integration files

Phase 4.1: Auth/utils extraction
- Created auth.py module with JWT validation and security utilities
- Created utils.py module with common helpers

Phase 4.2: Router decomposition
- Decomposed router.py into 10 domain modules (58 endpoints)
- Created route table snapshot for verification
- Preserved router_old.py as reference

Phase 5: App shell classification
- Documented app shell patterns across services

Phase 6: Quality gates
- Verified mypy type checking (75% error reduction)
- Analyzed logging inconsistencies with structlog migration plan
- Removed unused orjson dependency

Documentation:
- Created comprehensive remediation report
- Added architecture documentation for DI pattern
- Added quality analysis documents
