[Glossary entry] bridgelet-product-audit/glossary/sender-vs-recipient-auth-models.md: How sender authentication differs from recipient (claim) authentication

[phertyameen]

Glossary entry: bridgelet-product-audit/glossary/sender-vs-recipient-auth-models.md

Purpose:
Document the two distinct auth models operating in this product: sender-side wallet auth versus recipient-side claim-token auth.

This file should cover:

• Cross-reference docs/sender-auth-model.md for the sender side (Option B, wallet-based, no JWT).
• Describe the recipient side conceptually: a claim token/URL rather than a connected wallet is the credential for the claim flow.
• Note where these two models intersect: a recipient may ultimately need to connect a wallet too, once claiming funds into a permanent account.

Scope: documentation-only addition to a new, standalone folder. No changes to frontend/ or mobile/ are needed to close this issue.
