chore: bump main examples & lib to react-native@0.80 (#2970)

## Description

Should be merged after #2825

After 0.80.0-rc.2 we do not require any library code changes. The apps
must be updated, but thats it.

> [!caution] 
I'll proceed here, ignoring the detox, so that we can work with recent
RN versions in our apps.

## Changes

Updated example apps following the upgrade helper.

## Test code and steps to reproduce

Apps should build just fine.

## Checklist

- [❌] Ensured that CI passes
