fix: update agent and wallet API endpoints, improve RPC error handling, and mark additional CLI commands as working

- Update agent execute endpoint to use /v1/agents/workflows/{id}/execute path
- Add workflow_id and inputs fields to agent creation and execution payloads
- Accept both 200 and 201 status codes for agent create, network create, and contribution submit
- Update wallet balance and send RPC endpoints to use rstrip('/') instead of replace('/api', '')
- Add chain_id parameter to wallet R
