refactor: remove the unused submitUserInfo method and enhance the searchable dropdown functionality

- Removed `submitUserInfo` from auth services and integrations.
- Refined dropdown with new multi-select and searchable options.
- Added `PersianFormatter` for better input handling.
- Updated `local.properties` to set flutter build mode to debug.

+/// - [isOpen]: Reactive boolean indicating if the overlay is visible

+/// Example usage:
+/// ```dart
+/// final controller = SearchableDropdownLogic<String>(
+///   items: ['Item 1', 'Item 2', 'Item 3'],
+///   singleSelect: true,
