Subject: feat: fallback model range slider with live label, model-changed
 event

- Added model-changed event: backend emits it on fallback, frontend updates tab keyId/modelId
- Range slider embedded inside active agent card when >1 model configured
- Live label updates on drag (oninput), backend call only on release (onchange)
- Slider auto-positions when fallback occurs via model-changed WS event
