feat: implement CLI blockchain features and pool hub enhancements

CLI Blockchain Features:
- Added block operations: import, export, import-chain, blocks-range
- Added messaging system commands (deploy, state, topics, create-topic, messages, post, vote, search, reputation, moderate)
- Added network force-sync operation
- Replaced marketplace handlers with actual RPC calls
- Replaced AI handlers with actual RPC calls
- Added account operations (account get)
- Added transaction query operations
- Added mempool query operations
- Created keystore_auth.py for authentication
- Removed extended features interception
- All handlers use keystore credentials for authenticated endpoints

Pool Hub Enhancements:
- Added SLA monitoring and capacity tables
- Added billing integration service
- Added SLA collector service
- Added SLA router endpoints
- Updated pool hub models and settings
- Added integration tests for billing and SLA
- Updated documentation with SLA monitoring guide
