fix: temporarily disable routers to isolate Pydantic validation issue and add agent endpoints to working routers

- Comment out most routers in main.py to isolate Pydantic issue
- Keep only blockchain router enabled for testing
- Fix database warmup to use get_session() instead of SessionDep()
- Add blockchain router to __init__.py exports
- Add test endpoint to agent_router for verification
- Duplicate agent network and execution receipt endpoints in client and exchange routers as temporary workaround
