Fix Stage 7 issues based on analysis

- Add currency field (AIT) to cross_chain_transfer, staking_validator_agent, cross_chain_market_maker
- Add wallet_balance check at beginning of operations (before wallet/password operations)
- Add agent_create operations before agent_coordination_leader_election (3 agents)
- Add enterprise_create operation before enterprise_ai_agent
- Update agent_to_agent_message to use agent_* patterns instead of hardcoded agent_1, agent_2
