fix: Properly zoom in all matrix sizes

[bdlukaa]

This PR fixes an issue that would not let the software zoom work properly on matrix sizes other than 4x4.

• Software zoom now works in any matrix size;
• Zooming in and out is now supported on the web and on embedded devices;
• Correctly apply the local matrix size when edited.

Additionally, some updates to the settings were made:

• Implemented a value overrider. This is useful when a property needs to have a forced value at a specific platform or due to an environment limitation. It is used to ensure macOS, web and embedded will always use software zoom;
• Show an "Are you sure?" dialog when the user tries to restore all the settings options to the default. It is also marked as a destructive action;
• Implemented "choose download location for each download" option. When enabled, the user will be prompted to choose the download location for each download.
