Intergrate shared KMP module into the iOS app

[0xtmphey]

This PR wires android:shared KMP module to the iOS app and makes it possible to open KMP screens. Should be noted that the locker screen opens as a modal above the flutter app and its not the proper navigation solution :)

Changelog:

• Update shared module's gradle config to make Room work on iOS
• Implement AppDatabase.ios.kt
• Run shared:embedAndSignAppleFrameworkForXcode gradle task during Xcode build to integrate kmp binary into the iOS app (build times are longer now)
• Setup KMPApiBridge

It sounds like you have JDK 23 installed which the current version of Gradle/Kotlin doesn't support. I believe if you lower the JDK version Gradle is using to 17 you should be fine. You can change this in Android Studio via Settings | Build, Execution, Deployment | Build Tools | Gradle | Gradle JDK

[louwers]

I am not using Android Studio. I am using Xcode.

But yeah installing OpenJDK 17 and setting

 export JAVA_HOME=$(/usr/libexec/java_home -v 17)

Did the trick. That should be added to the README perhaps?
