refactor: separate Google Play and F-Droid functionality in parental control

This commit refactors the parental control components in the application by separating the Google Play and F-Droid related functionalities. It also renames and reorganizes the relevant classes and methods to improve readability and maintainability.

The `/data/blockedApps` directory no longer holds the classes for parental control because of their difference in functionality. Instead, `/data/parentalcontrol` directory contains the related classes.
