Outdated and inconsistent dialogs in settings

Describe the bug Some of the dialog menus used in the settings are outdated and look out of place. They don't follow the Material You color palette and instead have a Material 2 design.

To Reproduce Steps to reproduce the behavior:

1. Go to 'Settings'
2. Click on 'Number of decimal places' or 'Results saved in history'
3. See the old dialog/fragment

Expected behavior They should be similar to the dialog menu used for the 'Theme'.
