Widgets don't use text size defined in the settings

When a user changes the text size in Settings, all the notes show with the corresponding text size defined in settings. However, the widgets show the normal text size, they are not affected by the configuration.

### What

Make the widgets use the text size configuration defined in Settings by the user.

### Why

So the user can see the same size of their notes in their widgets.

Start by tracing how Android widgets render note text and how the text-size value from Settings is applied to regular notes. Compare those paths to identify where the widget ignores the configured size. Done means widgets display notes at the user-selected text size, matching notes in the app; verify this after changing the setting.
