chore(phase0): eBay 세트 제거 — 문진·문서 admin/API/lib/CONTENT + cheerio

Delete:
- app/api/questionnaire/ (submit/route.ts)
- app/admin/questionnaire/ (page.tsx)
- app/api/admin/questionnaire/ (route.ts + [id]/route.ts)
- app/admin/documents/ (page.tsx)
- app/api/admin/documents/ ([filename]/route.ts)
- lib/ebay-tools/ (crawler.ts·pricing.ts·ai-analyzer.ts·types.ts)
- CONTENT/ebay-tool-{questionnaire,proposal}.html
- CONTENT/ARCHITECTURE_EBAY_PARTS_TOOL.md

Modify:
- app/admin/components/AdminSidebar.tsx: Remove NAV_ITEMS for /admin/documents & /admin/questionnaire
- package.json: Remove cheerio dependency

Verify: npm test (4 files, 20 tests PASS), npm run build OK
