feat(snipe): parallel search+comps, pagination, title fix, price flag fix

- Parallel execution: search() and get_completed_sales() now run
  concurrently via ThreadPoolExecutor — each gets its own Store/SQLite
  connection for thread safety. First cold search time ~halved.

- Pagination: SearchFilters.pages (default 1) controls how many eBay
  result pages are fetched. Both search and sold-comps support up to 3
  parallel Playwright sessions per call (capped to avoid Xvfb overload).
  UI: segmented 1/2/3/5 pages selector in filter sidebar with cost hint.

- True median: get_completed_sales() now averages the two middle values
  for even-length price lists instead of always taking the lower bound.

- Fix suspicious_price false positive: aggregator now checks
  signal_scores.get("price_vs_market") == 0 (pre-None-substitution)
  so listings without market data are never flagged as suspicious.

- Fix title pollution: scraper strips eBay's hidden screen-reader span
  ("Opens in a new window or tab") from listing titles via regex.
  Lazy-imports playwright/playwright_stealth inside _get() so pure
  parsing functions are importable without the full browser stack.

- Tests: 48 pass on host (scraper tests now runnable without Docker),
  new regression guards for all three bug fixes.
