Enhance IBC tests with improved debugging and checksum handling

- Added debug print statements to log JSON data being sent to contracts and the code ID of the stored reflect contract.
- Updated checksum handling to convert the first 8 bytes to a uint64 for the reflect contract's code ID.
- Removed commented-out code related to message processing in the IBC packet dispatch test for clarity.
