eth: harmonize large data warnings for transactions and typed messages

This commit changes how the BitBox02 hardware wallet warns users about very large Ethereum transaction data and typed messages. Previously, large transaction data was shown only as a byte count with the message 'too large to display.' Now …

eth: implement streaming for typed data messages

This commit extends an existing Ethereum data-streaming feature so it also works for EIP-712 typed messages with large data fields (e.g., a 50 KB 'bytes' field). Previously, only large Ethereum transaction data could be streamed in chunks;…

New protocol field `data_length` gated by size thresholdStreaming restricted to dynamic `bytes` type; other types rejected with `Error::InvalidInput`Maximum streaming length capped at 1 MB (`MAX_TYPED_MSG_STREAMING_DATA_LENGTH`)

eth: add tests with large data to test streaming

This commit is purely a test-suite update for the BitBox02 hardware wallet's Ethereum transaction signing. It adds unit tests that verify the new 'streaming' mode for large transaction data produces the same cryptographic signatures as the…

eth: prepare and generate proto files for data streaming

This commit adds new message definitions and generated code to support streaming large Ethereum transaction data in chunks, but it does not implement the actual streaming logic. Existing tests are updated only to include the new optional f…
