remove nestjs-query auto-resolver from index-metadata (#22775)

## Summary

Removes the `NestjsQueryGraphQLModule.forFeature` block from
`IndexMetadataModule`, continuing the incremental migration off
`@ptc-org/nestjs-query`.

- Drops the dead auto-generated read surface: `index` and
`indexMetadatas` queries, the `IndexConnection` /
`IndexObjectMetadataConnection` types, and the `Index.objectMetadata`
field. No client consumes these — the frontend reads indexes via
`ObjectMetadata.indexMetadatas`.
- Keeps `IndexMetadataDTO` nestjs-query-compatible (`@Authorize`,
`@FilterableField`, `@QueryOptions`, `@IDField`) because
`ObjectMetadataDTO` still references it via
`@CursorConnection('indexMetadatas')` until object-metadata is migrated.
- Hand-written `createOneIndex` / `deleteOneIndex` mutations and the
`indexFieldMetadataList` resolve-field are unchanged.
- Deletes the now-obsolete `index-metadatas` integration test and
regenerates the GraphQL schema artifacts (frontend + client-sdk).

## Breaking change

This is an intentional GraphQL schema breaking change
(`api-breaking-changes` CI will flag it)
