fix: correct CampaignsView, analysis.py IPv4 split, entities date filter

- CampaignsView: update ClusterData interface to match real API response
  (severity/unique_ips/score instead of threat_level/total_ips/confidence_range)
  Fix fetch to use data.items, rewrite ClusterCard and BehavioralTab
  Remove unused getClassificationColor and THREAT_ORDER constants
- analysis.py: fix IPv4Address object has no attribute 'split' on line 322
  Add str() conversion before calling .split('.')
- entities.py: fix Date vs DateTime comparison — log_date is a Date column,
  comparing against now()-INTERVAL HOUR caused yesterday's entries to be excluded
  Use toDate(now() - INTERVAL X HOUR) for correct Date-level comparison
