Expiration Time for Child IPs Not Exceed Parent IP

[kingster-will]

Description

This PR addresses the issue where the expiration time of a Child IP could exceed the expiration time of its Parent IP, which contradicts the intended inheritance of expiration constraints from parent to derivative IPs.

Key Changes

• Modified the derivative registration logic to ensure that the expiration time of the Child IP is either equal to or earlier than that of the Parent IP.

Test Plan

• Updated tests to include scenarios where the Parent IP has a shorter expiration time than the license terms to which a Child IP registers.

Yes, I confirmed with @jzhao23 that this is expected behavior from a product perspective that the Child IP should not be active after the Parent IP expires.
