Subject: [PATCH] Fix NullPointerException in enqueue actions by using
 Application Context

Use getApplicationContext() instead of getContext() in ENQUEUE,
ENQUEUE_NEXT, START_HERE_ON_BACKGROUND, and START_HERE_ON_POPUP
entries to prevent NullPointerException when the fragment's activity
context becomes null during configuration changes (e.g. device rotation).

The fragment context can become null when the activity is destroyed
during rotation, but the async callback from fetchItemInfoIfSparse
still holds a reference to the now-detached fragment. Using
Application context ensures a stable, non-null context throughout
the async operation lifecycle.
