[bug]: SDK Bug: blobMerkleRoot bytes with value 0x00 converted to null instead of 0

[mistermc7899]

Affected product

SDK (JS/TS)

Version / Commit / Build

0.0.7

Platform / Environment

Browser (Chrome)

Steps to Reproduce

1. Use @shelby-protocol/sdk version 0.0.7
2. Try to upload a file whose merkle root contains 0x00 bytes
3. Example merkle root: "0xa63afed6d85f2be676402661ebfa1516c6e41c4536a8c43bb09cbd9be700b1bd"
4. The transaction simulation will fail in the wallet

Expected Behavior

The blobMerkleRoot hex string should be converted to a byte array where 0x00 becomes 0:
[166, 58, 254, ..., 231, 0, 177, 189] (position 29 = 0)

The transaction should simulate successfully and the file should upload.

Actual Behavior & Errors

The blobMerkleRoot hex string is converted to a byte array where 0x00 becomes null:
[166, 58, 254, ..., 231, null, 177, 189] (position 29 = null)

Error: Simulation error: Type mismatch for argument 2, expected 'number | string'

The transaction simulation fails and the file cannot be uploaded.
