Add optional memo field (proto field 7) to RippleSignTx. Firmware changes: - messages-ripple.options: add RippleSignTx.memo max_size:200 - ripple.c: serialize XRPL Memos array (STArray[9]/STObject[10]/MemoData VL[13]) after destination in canonical XRPL field order - fsm_msg_ripple.h: display memo on confirmation screen before signing THORChain swap memos (e.g. '=:ETH.ETH:0x...') are stored as raw UTF-8 bytes in the XRPL MemoData VL field, following the XRPL binary format spec.
deps/device-protocol → 8ef74da (feat(ripple): memo + THORChain routing) deps/python-keepkey → bf870e6 (7.14.2: XRP memo + EVM depositWithExpiry + msg-signing)
