Add shareable search links with saved filters

Save a search and get a shareable URL at /share/<id> that preserves:
- Search query
- Selected stores
- Filter text
- Excluded stores
- Sort column and direction

Backend:
- New shared_searches table (migration 005)
- POST /api/share — saves search state, returns share_id
- GET /api/share/:id — loads saved search config

Frontend:
- Share button appears on results page after search completes
- Copies link to clipboard with confirmation message
- /share/[id] page loads saved config, re-runs search with same
  store selection, and restores all filters
- Shows "Shared" badge in header with "Search Again" link
