Improve driver list data handling and filtering

Refactors the driver selection UI to enhance stability and performance by changing how the underlying data source is managed. Creating and re-assigning a new list when data changes, rather than modifying the bound collection in-place, prevents UI inconsistency errors.

- Updates the model search to use the native WPF `CollectionView.Filter` for more efficient and reliable filtering.
- Fixes an issue where HTML entities were not decoded in Microsoft driver model names.
- Ensures selected drivers from one manufacturer are preserved when fetching models for another.
- Centralizes driver-related button event handlers into the core initialization module.
