Rene Fichtmueller f8809d999f feat(scraper+api): warehouse stock data pipeline — FS.com v2, SmartOptics v2, Stock API
Scraper changes:
- fs-com.ts v2: Playwright stealth patches + www.fs.com/de/ URL fix (de.fs.com DNS NXDOMAIN).
  Extracts DE-Lager, Global-Lager, Nachlieferung, units_sold, compatible_brands, price_net.
  Mac-side runner (run-fs-scraper-mac.sh) via SSH tunnel for residential IP access.
  Fast-fail connectivity check on datacenter IPs that are blocked by Cloudflare.
- smartoptics.ts v2: WooCommerce REST API fallback + 8 catalog categories + relative URL fix.
  Was finding only 8 products, now discovers 18+ with multi-category crawl.

DB layer:
- db.ts: add upsertStockObservation() — writes 10 new stock_observations columns
  (warehouse_de_qty, warehouse_global_qty, backorder_qty, units_sold, compatible_brands,
  price_net, product_url, delivery dates) with dedup check.

API:
- routes/stock.ts: GET /api/stock, /api/stock/summary, /api/stock/:id
  Warehouse breakdowns per transceiver/vendor with top-sellers and vendor summary.
- routes/review.ts: equivalence review queue (approve/reject/bulk-approve).
- index.ts: register /api/stock and /api/review routes.

Dashboard:
- index.html: 🏭 Stock tab with stat cards (DE-Lager, Global-Lager, Nachlieferung totals),
  top-sellers table, vendor breakdown, recently-restocked events, part-number lookup.

SQL migrations:
- 034: blog-review-tag, 035: price-observations is_anomalous, 036: transceiver-equivalences.
