Implementing ScamScreener to Wizard and Fixed persistence of background image

[Pankraz01]

Summary

This PR integrates ScamScreener into the welcome wizard through its published API. And fixes the background image not saved properly.

Whats Changed

• Added an optional ScamScreener integration to PackCore

• Applied wizard selections through the API for:

  • Minimum Alert Risk Level
  • Ping On Risk Warning
  • Ping On Blacklist Warning

• Made the available alert levels dynamic so the wizard stays compatible with future ScamScreener changes

• Only show the ScamScreener wizard step when ScamScreener is actually installed

Fixes

• Fixed the post-wizard flow so PackCore opens the newly selected title screen immediately after finishing setup
• Fixed a startup crash caused by a missing changelog string in the title screen overlay

ScamScreener can evolve independently from PackCore. Reading available settings from the API avoids config drift and makes the wizard more robust across ScamScreener updates.

Testing

• ./gradlew build
• Wizard Test

Note

Could not test other features of wizard. didn't know what else i need to test it. most of the time it showed some placeholders.
