Implemented another protection when removing signed policies in AppControl Manager

[HotCakeX]

This new protection mechanism ensures the safe removal of signed policies. To complete the process securely, a system reboot is required after the first stage. The newly implemented protection verifies that the reboot has been performed before allowing the process to proceed to the final stage.

If the user forgets to reboot or is unsure whether it’s necessary, a prompt will appear to guide them through the process. This safeguard prevents accidental errors that could lead to boot failures, making the AppControl Manager even safer and more reliable when managing Signed App Control policies.

• The calculation for 'lastRebootTimeUtc' might be incorrect if 'Environment.TickCount64' overflows. Handle this case to avoid potential issues.

DateTime lastRebootTimeUtc = DateTime.UtcNow - TimeSpan.FromMilliseconds(Environment.TickCount64);

AppControl Manager/Logic/Main/UserConfiguration.cs:391

• The use of '[]' for initializing the dictionary is incorrect in C#. It should be 'new Dictionary<string, DateTime>()'.
