Sanitize Input for Hidden Control Characters and Whitespace

[codeZe-us]

Copy-pasting addresses from block explorers or PDFs often introduces invisible Unicode characters, zero-width spaces, or carriage returns. This currently causes false-positive "invalid address" errors.

• Add a preprocessing step to extractRouting that aggressively strips non-printable characters and trims whitespace from the destination string.
• Log a SANITIZED_HIDDEN_CHARS info-level warning to inform developers of the modification.
• Add test vectors featuring malicious/invisible Unicode characters.

Expectation: The kit is highly robust against messy user input, reducing user frustration when pasting addresses from varying operating systems and platforms.
