🚀 feat: Introduce full Model & Vendor Management suite (backend + frontend) and UI refinements

Backend
• Add `model/model_meta.go` and `model/vendor_meta.go` defining Model & Vendor entities with CRUD helpers, soft-delete and time stamps
• Create corresponding controllers `controller/model_meta.go`, `controller/vendor_meta.go` and register routes in `router/api-router.go`
• Auto-migrate new tables in DB startup logic

Frontend
• Build complete “Model Management” module under `/console/models`
  - New pages, tables, filters, actions, hooks (`useModelsData`) and dynamic vendor tabs
  - Modals `EditModelModal.jsx` & unified `EditVendorModal.jsx`; latter now uses default confirm/cancel footer and mobile-friendly modal sizing (`full-width` / `small`) via `useIsMobile`
• Update sidebar (`SiderBar.js`) and routing (`App.js`) to surface the feature
• Add helper updates (`render.js`) incl. `stringToColor`, dynamic LobeHub icon retrieval, and tag color palettes

Table UX improvements
• Replace separate status column with inline Enable / Disable buttons in operation column (matching channel table style)
• Limit visible tags to max 3; overflow represented as “+x” tag with padded `Popover` showing remaining tags
• Color all tags deterministically using `stringToColor` for consistent theming
• Change vendor column tag color to white for better contrast

Misc
• Minor layout tweaks, compact-mode toggle relocation, lint fixes and TypeScript/ESLint clean-up

These changes collectively deliver end-to-end model & vendor administration while unifying visual language across management tables.
