fix(analytics): resolve null screen and call site in release error modals

R8 strips Kotlin metadata and source file attributes from coroutine
continuations, causing screenName() and showError() call site capture
to produce null values. Switch screen resolution to Java reflection
with a ProGuard keep rule for AppRoute names, and fall back to the
outer class name when source file info is unavailable.
