fix: chat WS relay URL + chat UX improvements

- Fix docker-compose to read GATEWAY_WS_URL (was VITE_WS_URL, never set)
- Fix gateway-relay.ts default to ws.hammer.donovankelly.xyz
- Fix Elysia TS errors in error handlers (cast to any)
- Add thinking/typing indicator in chat (bouncing dots)
- Add message timestamps (tap to show)
- Add thread renaming (double-click thread name)
- Auto-resize chat input textarea
