Add test for aclToGrants() function that converts ACL rules to Grant
format. Tests conversion of:
- Single-port TCP rules
- Multiple ACL entries to multiple Grants
- Port ranges and multiple ports in a single rule
- Wildcard protocols
- UDP, ICMP, and other protocol types
Ensures backward compatibility by verifying that ACL rules are correctly
transformed to the new Grant format.
