Prevent UI freezes during sync by batching wallet transaction notifications
with a 250ms debounce timer and full-refresh fallback for large batches.
Disable dynamic sorting and view updates on overview/transaction pages while
syncing. Add request/reply/error filter checkboxes to the RPC console with
in-memory message store. Implement macOS LaunchAgents-based autostart.
