Delta Customization Module

Delta Customization (Tabs + Theme + QoL) * Saves your Delta tabs (script1.lua, script2.lua, etc.) to files and auto-loads their code. * Replaces Delta’s draggable icon system with a smoother drag system and optional RGB outline toggle inside the settings menu. * Adds new settings for sidebar colors: active/inactive button colors and a 2-color gradient, all with C/D toggles and saved to `DeltaCustom/Colors.json`. * Adds a “Copy Code” button to the executor, and a fixed ping display
