Description

This PR updates the GraphQL schema and types related to segments and campaigns. The main changes are:

• Update the Segment fragment to use the Segment type instead of SegmentsEntry
• Update the Segments query to return code and name fields directly, instead of using the Segment fragment
• Add an adSetCount field and adSets arguments to the Campaign type
• Add an AdSetFilter input type to filter ad sets by name
• Add an AFFILIATE enum value to CampaignType
• Remove some unused fields from the OS and Segment types

The motivation seems to be to clean up the schema and add some new functionality around ad sets and campaign types.
