fix(views): align SQL views with dashboard API expected columns
- view_form_bruteforce_detected: add post_count, distinct_paths, first_seen, last_seen
- view_host_ip_ja4_rotation: add host, distinct_ja4, ja4_list, window_start
- view_ip_recurrence: add worst_threat alias + top_ja4, top_host columns
All three views were missing columns referenced by /api/brute-force,
/api/ja4-rotation and /api/recurrence endpoints, causing 500 errors
on the Tactiques page.
