refactor(web): migrate from Next.js to Vite + React Router (#2102)

* refactor(web): migrate from Next.js to Vite + React Router

* fix: update build pipelines for Vite migration (out → dist)

- Dockerfile: npm run build → npx vite build, web/out → web/dist
- pyproject.toml: package-data web/out/** → web/dist/**
- paths.py: support both web/dist (Vite) and web/out (legacy) with fallback

* fix: remove .next from git tracking, add to .gitignore

1334 cached files from web/.next/ were accidentally committed.
Added .next/ to both root and web/.gitignore.

* fix: update build process to use Vite and correct output directory

* fix: update pnpm-lock.yaml and eslint config for Vite migration

* style: fix prettier formatting issues

* fix: add eslint-plugin-react-hooks for Vite migration

* fix: remove undefined eslint rule reference, downgrade react-hooks plugin to v5

* fix(web): clean up remaining Next.js artifacts in Vite migration

- Add vite-env.d.ts for import.meta.env and asset type declarations
- Remove dead layout.tsx (providers already in main.tsx)
- Fix useSearchParams destructuring to [searchParams] tuple (11 locations)
- Replace process.env.NEXT_PUBLIC_* with import.meta.env.VITE_*
- Fix langbotIcon.src to langbotIcon (Vite returns URL string)
- Fix Link href to Link to for react-router-dom
- Fix navigate({ scroll: false }) to { preventScrollReset: true }
- Fix [router] dependency arrays to [navigate]
- Remove Next.js plugin from tsconfig, set rsc: false in components.json
- Replace next lint with eslint in lint-staged

* feat: add tools API endpoint and tools-selector form type

Backend:
- Add GET /api/v1/tools — list all available tools (plugin + MCP)
- Add GET /api/v1/tools/<tool_name> — get specific tool details

Frontend:
- Add TOOLS_SELECTOR form type for plugin config forms
- Multi-select dialog with tool name and description
- Add PluginTool entity type and API client methods

* Revert "feat: add tools API endpoint and tools-selector form type"

This reverts commit 3c637fc563.
