Updated Test screen to compose

[LagradOst]

• Added new UI for the testing screen, this includes: search filtering and a dialog
• Added ImmutableState to have a generic persistent state for searching and filtering
• Refactored the existing tests to allow to read the logcat while running tests
• Refactored Logcat to use it in both testing and android logcat

This pr mostly added the required components to update the extentions UI.
