Bug Report: Apprise "Newly Found Node" notifications never fire for Meshtastic nodes

Description

Apprise notifications are configured and working (test notifications and traceroute notifications both deliver successfully), but "Newly Found Node" notifications are never sent for Meshtastic nodes.

Root cause identified by user: notifyNewNode is never called for Meshtastic nodes.

Steps to Reproduce

1. Configure Apprise notifications with a Discord webhook
2. Enable "Newly Found Messages" in notification settings
3. Have a new Meshtastic node appear on the mesh

Expected Behavior

An Apprise notification is sent when a new Meshtastic node is discovered.

Actual Behavior

No notification is sent. notifyNewNode is not called for Meshtastic nodes. Other notification types (test, traceroute) work correctly.

Environment

• Apprise enabled with Discord webhook
• "Newly Found Messages" checkbox is checked
• Other Apprise notification types confirmed working
