Conversation
When ABI decoding fails, attempt to decode the hex input as UTF-8 text. If ≥80% of characters are printable, show the decoded text above the raw hex in a readable pre-formatted block. This handles text messages embedded in transactions like the Ethereum Foundation mandate. Closes openscan-explorer#311

Description
When transaction input data is not an ABI-encoded function call, attempt to decode it as UTF-8 text. If the result is mostly printable characters (≥80%), display it in a readable pre-formatted block above the raw hex.
