Cedar Games - Carrier Header Enrichment

This service handles carrier header enrichment for automatic subscriber detection.

Endpoints:

• /api/carrier/header-enrichment - Main HE endpoint (HTTP only)
• /api/carrier/header-enrichment?mode=inspect - Debug header inspector

How it works:

1. User visits via Hutch mobile data (HTTP, not HTTPS)
2. Carrier gateway injects MSISDN header
3. Server reads header, creates token
4. Redirects to /subscribe with token
