🚀 Improvements

Slicer major G-code preview performance improvements — eliminated post-parse freezing, chunked rendering, reduced memory pressure on large files, and faster rendering through geometry grouping

Slicer modifier volumes are now hidden during slicing and preview for a cleaner view
Slicer slicer settings panel is hidden when you don't have the "change profile settings" permission
