feat: add search result click tracking and fix content engagement labels

- Pass search_query_id to search results template
- Add POST /api/analytics/search-click endpoint to update SearchQuery
  with clicked_result_position, clicked_company_id, time_to_click_ms
- Add data-position and data-company-id attributes to company cards
- Add JS using navigator.sendBeacon for non-blocking click tracking
- Fix content engagement labels: "nowych (30 dni)" instead of "opublikowanych"
