Add AppsScriptVariables functionality to UI for defining key-value pairs

- Introduced a new checkbox to enable defining Apps Script Variables.
- Added a panel for inputting key-value pairs with validation for duplicates.
- Implemented event handlers for adding, removing, and clearing Apps Script Variables.
- Updated LoadConfig logic to handle loading of Apps Script Variables from configuration.
