Why:
• The vendor list API is separate from the models API, causing the “Vendor” column in `ModelsTable` to flash (rendering `'-'` first, then updating) after the table finishes loading.
• This visual jump degrades the user experience.

What:
• Updated `web/src/hooks/models/useModelsData.js`
  – In the initial `useEffect`, vendors are fetched first with `loadVendors()` and awaited.
  – Only after vendors are ready do we call `loadModels()`, ensuring `vendorMap` is populated before the table renders.

Outcome:
• The table now renders with complete vendor data on first paint, removing the flicker and providing a smoother UI.
