Push notifications broken - mobile devices not receiving notifications

Description

Push notifications from Claude Code are not being delivered to linked mobile devices.

Steps to reproduce

1. Link a mobile device (iPhone) to Claude Code via the Claude iOS app
2. Enable push notifications via /config → "Push when Claude decides"
3. Run a long-running task in Claude Code
4. No push notification is received on the device

Expected behavior

Mobile device receives a push notification when Claude completes a task or needs input.

Actual behavior

No notifications are delivered. The device appears linked but notifications do not arrive.

Environment

• Platform: Windows 11
• Claude Code version: (latest)
• Device: iPhone (iOS)

Additional context

Related: The Claude iPad app does not show a "Claude Code" section at all (only iPhone does), so iPad cannot be linked to Claude Code remote control sessions. This may be a separate issue but could share the same underlying cause.
