feat: search and import new parts scraped from pc-builder.io

Idealo and PCPartPicker were evaluated and ruled out:
- idealo.fr search pages return 503 (Cloudflare)
- the internal Idealo GraphQL endpoint used by a public scraper
  (app.idealo.de/app-backend/api) is protected by Akamai Bot Manager and
  silently returns empty data even with mobile app headers
- PCPartPicker's product list/search relies on a session-bound CSRF token
  refreshed per page load, against a scraping-hostile ToS

pc-builder.io category pages are server-rendered, include name/price/image
for ~100 products per category, and have no bot protection, so the feature
is built on top of that source only.

- New scraped_parts cache table (type_id, name, price, image_url, source,
  source_url, source_ref unique per source) populated by a batch job
  rather than scraped live per search, since only ~100 first results per
  category are available without reverse-engineering pc-builder.io's
  DataTables/CSRF pagination flow
- part_scraper_service.ts: maps our ComponentType names to pc-builder.io
  category slugs (SSD -> storage, since pc-builder.io has no separate HDD
  category) and parses each category page with cheerio, skipping rows
  without a resolved price (generic 'search on Amazon' links)
- node ace scrape:parts: refreshes the cache for every mapped category
  (upsert on source+source_ref), runnable manually or later via cron
- GET /scraped-parts (authenticated): search the cache by name (LOWER()
  LIKE, avoids a MySQL utf8_bin/utf8mb4 collation mismatch from Lucid's
  whereLike) and optional typeId filter
- NewPartSearch.vue: debounced search widget wired into
  components/create.vue; clicking 'Import' pre-fills the existing
  component creation form (name, price, type, purchase date = today)
  instead of creating the Component directly, so the user still reviews
  and saves it like any manually entered part
- 3 functional tests covering search by name, filter by typeId, and
  unauthenticated access being redirected to login
- Initial scrape run: 989 parts across 10 categories
