Personal Settings no longer needs to fetch `/api/user/models` since models are now displayed directly. This change removes the unused data flow to simplify the component and avoid unnecessary requests.

Changes:
- Removed `models` and `modelsLoading` state from `web/src/components/settings/PersonalSetting.jsx`
- Removed `loadModels` function and its invocation in the initial effect
- Kept UI behavior unchanged; no functional differences on the Personal Settings page

Notes:
- Lint passes with no new issues
- Other parts of the app still using `/api/user/models` (e.g., Tokens pages) are intentionally left intact

Rationale:
- Models are already displayed; the API call in Personal Settings became redundant
