Detailed Description

Edit Contact Name flow (P1=0x02, struct type 0x2e)

Allows changing the CONTACT_NAME of an existing Identity contact. Because HMAC_PROOF covers only (gid, name), the wallet does not need to transmit the identifier, scope, or network fields.

Flow:

1. Parse TLV payload (gid + new_name + previous_name + derivation_path + hmac_proof)
2. Verify HMAC_PROOF over (gid, previous_name)
3. Display UI: old name → new name
4. On confirm: compute new HMAC_PROOF over (gid, new_name) and send

Active under HAVE_ADDRESS_BOOK.
