• Implemented filter toggle behavior:
  • Selecting a chip applies the filter
  • Selecting the active chip again clears the filter
• Updated historyLogs flow to combine:
  • Search query filtering
  • Action-based filtering
• Removed string-based tab filtering logic in favor of strongly typed RuleAction filtering

HistoryScreen

• Added filters for:
  • Blocked (RuleAction.BLOCK)
  • Muted (RuleAction.MUTE)
  • Delivered (RuleAction.ALLOW)
• Connected chip selection state to the ViewModel
• Preserved existing search functionality while supporting combined search + action filtering

Behavior
