fix: correct message hashing for signature verification

- Fixed hashMessage function to not add extra length byte before message prefix
- The prefix '\x19DigiByte Signed Message:\n' already contains the length indicator
- Enhanced public key recovery to try all 4 recovery IDs for better compatibility
- Verified with both beta.0 and beta.1 test data
- All tests passing
