* Request: ask device to sign TON transaction

* Two modes:
* 1. Clear-signing (preferred): provide to_address + amount + seqno + expire_at.
* Device reconstructs the v4r2 unsigned body cell, computes its hash,
* and verifies it matches raw_tx before signing. Shows "TON Transfer"
* confirmation with verified amount and recipient.
*
* 2. Blind-signing (fallback): provide only raw_tx. Device signs the hash
* directly with a blind-sign warning. Used for non-standard transactions.
