fix(room): show model name instead of UID in settings panel

- Load model list on settings panel mount so names are always available.
- SelectValue now displays the selected model's name by looking up
  availableModels, falling back to UID if name not found.
- Existing AI configs list also shows model name instead of raw UID.
