fix: correct proto imports and test assertions for TRON, TON, Solana, BIP-85

- TRON/TON signtx: import gate checked messages_pb2 but messages live in
  messages_tron_pb2/messages_ton_pb2 — tests were silently skipping
- TRON/TON signtx: message constructors used messages.Tron*/Ton* instead
  of tron_messages.Tron*/ton_messages.Ton*
- Solana signtx: used dummy b'\x11'*32 as signer pubkey instead of
  querying the actual derived key — firmware rejected "not a signer"
- BIP-85: removed set_expected_responses (firmware sends variable number
  of ButtonRequest_ConfirmWord for mnemonic display pages)

Dress rehearsal: 44 passed, 448 real 256x64 OLED screenshots captured.
