feat: add 7.14.0 proto bindings, client methods, and integration tests

Proto bindings (compiled with protoc 3.5.1 in Docker for CI compat):
- messages_pb2.py: regenerated with BIP-85 (120-121), Solana (750-755),
  Tron (1400-1403), TON (1500-1503) wire IDs
- messages_solana_pb2.py: SolanaGetAddress/Address/SignTx/SignedTx/SignMessage
- messages_tron_pb2.py: TronGetAddress/Address/SignTx/SignedTx
- messages_ton_pb2.py: TonGetAddress/Address/SignTx/SignedTx

Client methods (client.py):
- solana_get_address, solana_sign_tx, solana_sign_message
- tron_get_address, tron_sign_tx
- ton_get_address, ton_sign_tx

Mapping (mapping.py):
- Route Solana/Tron/TON message types to chain-specific proto modules
- Gracefully skip unknown types (e.g. Zcash not in 7.14.0)

Integration tests (14 new tests):
- test_msg_bip85.py: 12/24-word derivation, determinism, index isolation
- test_msg_solana_getaddress.py: address format, determinism, account isolation
- test_msg_tron_getaddress.py: T-prefix Base58, determinism, account isolation
- test_msg_ton_getaddress.py: address format, determinism, account isolation
