Description of the changes in your PR

Converted ErrorActivity from Android Views to Jetpack Compose. The XML layout and menu are replaced by a Compose screen with all the same sections: error message, device info, stack trace details, user comment field, and report/share actions. The privacy policy dialog was also converted to Compose so it survives rotation and renders correctly with Material 3 theming. A shared BaseActivity was introduced to provide edge-to-edge display and Compose theme setup, serving as the foundation for future activity migrations.

@theimpulson please checkout the new changes with the ComposeActivity. Also introduced an ErrorReportHelper containing those methods that were initially in the ErrorActivity. The settings screens already had an implementation with the NavDisplay so decided to just bring it in as well and get rid of the settings activity since this will serve as the central activity for all compose screens. There's the AboutActivity that needs to be gotten rid of as well but I think I will handle that in another pr.

Please don't use one word variable names

I am not sure but won't this keep looping back and forth in case of crash when ErrorActivity is launched by acra?

[theimpulson]

Why are we specifying these colors manually?

[theimpulson]

Please put variables before functions and classes similar to how we structure things in a class

Thank you, looks good to me other than some minor nitpicks and questions on places where I am unsure about the behavior.
