docs: rename embedding section to Self-Learning WiFi AI

Reframe the ADR-024 section header to emphasize AI self-learning and
adaptive optimization rather than technical CSI embedding terminology.

-Every WiFi signal that passes through a room creates a unique fingerprint of that space. WiFi-DensePose already reads these fingerprints to track people, but until now it threw away the internal "understanding" after each reading. The Contrastive CSI Embedding Model captures and preserves that understanding as compact, reusable vectors.

The Self-Learning WiFi AI captures and preserves that understanding as compact, reusable vectors — and continuously optimizes itself for each new environment.
 
 **What it does in plain terms:**
 - Turns any WiFi signal into a 128-number "fingerprint" that uniquely describes what's happening in a room
