fix(stores): align RPC methods with OpenClaw protocol and fix chat flow

- Fix channels store: use channels.status instead of channels.list
- Fix skills store: use skills.status instead of skills.list
- Fix chat store: correct chat.history response parsing (messages in payload)
- Fix chat store: handle chat.send async flow (ack + event streaming)
- Add chat event handling for streaming AI responses (delta/final/error)
- Wire gateway:chat-message IPC events to chat store
- Fix health check: use WebSocket status instead of nonexistent /health endpoint
- Fix waitForReady: probe via WebSocket instead of HTTP
- Gracefully degrade when methods are unsupported (no white screen)
