⚡ Bolt: Optimize Treeview Clearing Performance

[inherent-vice]

💡 What: Replaced loop-based individual deletions (tree.delete(item)) with batch deletions via unpacking (tree.delete(*tree.get_children())) across all applicable tabs. Included inline code comments to explain the optimization.
🎯 Why: Tkinter/CustomTkinter Treeview widgets suffer from major performance bottlenecks when iterating to delete children because the UI state updates or re-renders internally for each item. Batch deletion completes the operation in one swift underlying Tcl call.
📊 Impact: Reduces Treeview clearing times drastically for heavily populated lists (like operations logs, file lists, or status rows), eliminating UI freezes and ensuring a significantly faster rendering pass.
🔬 Measurement: Validated using static compilation checks and manifest consistency checks. The underlying improvement is a known characteristic of the Tcl/Tk engine underlying CustomTkinter. To verify, test UI data refresh with ~1000 items on OpsCockpitTab or QuickSearchTab and observe the reduced hang time.
