Add remote response notification for Loop

[codebymini]

Accept APNS responses from looping phone for remote carbs/bolus

Summary

This change makes the app properly accept APNS notifications sent back from a looping phone when a remote carbs and/or bolus request is issued. It ensures the notification path is valid, properly configured, and aligned with the remote-command settings flow so the response can be received reliably.

Details

• Aligns the remote command setup so APNS credentials and environment are handled consistently when communicating with the looping phone.
• Ensures the app is eligible to receive the push response for remote carbs/bolus actions.
  Adds supporting adjustments in the remote settings and notification handling flow to reduce failure cases in end‑to‑end remote responses.
