Move internal MCP server to backend, use Mintlify MCP for docs tools (#1389)
## Summary
- Move the `/api/internal/[transport]` MCP route from the docs app to
the backend, so the public `ask_stack_auth` MCP tool is served from the
same origin as the AI query API it proxies to.
- Replace the bespoke docs-tools HTTP client in
`apps/backend/src/lib/ai/tools/docs.ts` with an `@ai-sdk/mcp` client
that talks to Mintlify's generated MCP server. The backend AI agent now
consumes Mintlify's lower-level search/fetch tools directly instead of
going through the docs app.
- Swap `STACK_DOCS_INTERNAL_BASE_URL` for `STACK_MINTLIFY_MCP_URL`
(defaults to the Mintlify-hosted MCP URL).
- Move the `@vercel/mcp-adapter` dependency from `docs` to
`apps/backend`.

## Test plan
- [ ] `pnpm typecheck`
- [ ] `pnpm lint`
- [ ] e2e: new
`apps/e2e/tests/backend/endpoints/api/v1/internal/mcp.test.ts` covers
`tools/list` and validation on `tools/call`
- [ ] Manual: hit `POST /api/internal/mcp` on the backend and confirm
`ask_stack_auth` is listed and callable
- [ ] Manual: confirm backend AI agent docs tools resolve via the
Mintlify MCP URL
