Deflake the test by corrupting the first AES-CBC ciphertext byte instead of the final byte. Mutating the final byte made the decrypted padding block random, which could occasionally produce valid PKCS#7 padding and cause subtle.decrypt() to resolve. Mutating the first byte deterministically corrupts the padding block for this two-block ciphertext, so the expected OperationError rejection is stable.
