✨ feat: Improve models UX and robustness: add JSONEditor extraFooter, fix endpoints rendering, and clean up deps

- Why
  - Needed to separate help text from action buttons in JSONEditor for better layout and UX.
  - Models table should robustly render both new object-based endpoint mappings and legacy arrays.
  - Columns should re-render when vendor map changes.
  - Minor import cleanups for consistency.

- What
  - JSONEditor.js
    - Added optional prop extraFooter to render content below the extraText divider.
    - Kept extraText rendered via Divider; extraFooter appears on the next line for clear separation.
  - EditModelModal.jsx
    - Moved endpoint group buttons from extraText into extraFooter to display under the helper text.
    - Kept merge-logic: group items are merged into current endpoints JSON with key override semantics.
    - Consolidated lucide-react imports into a single line.
  - ModelsColumnDefs.js
    - Made endpoint renderer resilient:
      - Supports object-based JSON (keys as endpoint types) and legacy array format.
      - Displays keys/items as tags and limits the number shown; uses stringToColor for visual consistency.
    - Consolidated Semi UI imports into a single line.
  - ModelsTable.jsx
    - Fixed columns memoization dependency to include vendorMap, ensuring re-render when vendor data changes.

- Notes
  - Backward-compatible: extraFooter is additive; existing JSONEditor usage remains unchanged.
  - No API changes to backend.
  - No linter errors introduced.

- Files touched
  - web/src/components/common/ui/JSONEditor.js
  - web/src/components/table/models/modals/EditModelModal.jsx
  - web/src/components/table/models/ModelsColumnDefs.js
  - web/src/components/table/models/ModelsTable.jsx

- Impact
  - Clearer UI for endpoint editing (buttons now below helper text).
  - Correct endpoints display for object-based mappings in models list.
  - More reliable reactivity when vendor data updates.
