Detailed Description

Edit Scope flow (P1=0x04, struct type 0x32)

Allows changing the SCOPE of an existing Identity contact while keeping the same contact_name and identifier.

Flow:

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