Detailed Description

Edit Identifier flow (P1=0x03, struct type 0x31)

Allows changing the IDENTIFIER of an existing Identity contact while keeping the same contact_name and scope.

Flow:

1. Receive fully assembled payload (multi-chunk reassembly handled by address_book.c)
2. Parse TLV payload (contact_name + scope + new_identifier + old_identifier + gid + derivation_path + hmac_proof + hmac_rest)
3. Verify HMAC_PROOF over (gid, contact_name)
4. Verify HMAC_REST over (gid, scope, old_identifier, family[, chain_id])
5. Coin-app notification: handle_check_edit_identifier()
6. Display UI: contact name, old identifier → new identifier
7. On confirm: compute new HMAC_REST over (gid, scope, new_identifier, family[, chain_id]) and send to host
