♻️ refactor(hooks/models): deduplicate `useModelsData` and optimize vendor-tab counts

Highlights
──────────
1. Removed code duplication
   • Introduced `extractItems` helper to safely unwrap API payloads.
   • Simplified `getFormValues` to a single-line fallback expression.
   • Replaced repeated list-extraction code in `loadModels`, `searchModels`,
     and `refreshVendorCounts` with the new helper.

2. Vendor tab accuracy & performance
   • Added `refreshVendorCounts` to recalc counts via a single lightweight
     request; invoked only when必要 (current tab ≠ "all“) to avoid redundancy.
   • `loadModels` still updates counts instantly when viewing "all", ensuring
     accurate numbers on initial load and page changes.

3. Misc clean-ups
   • Streamlined conditional URL building and state updates.
   • Confirmed all async branches include error handling with i18n messages.
   • Ran linter → zero issues.

Result: leaner, easier-to-maintain hook with correct, real-time vendor counts
and no repeated logic.
