Pull request overview

Fixes schema validation for IsSelected pattern attributes used on non-root (non-Query) object types, preventing failures during schema build and adding a regression test to lock in behavior.

Changes:

• Update IsSelectedPatternValidation to resolve the target field from the declaring pattern type instead of schema.QueryType.
• Add a new resolver test exercising IsSelected pattern usage on a nested object type field.
• Add a snapshot for the new test result.

File	Description
src/HotChocolate/Core/src/Types/Configuration/Validation/IsSelectedPatternValidation.cs	Uses pattern.Type.Fields[...] so patterns on nested object types validate against the correct declaring type.
src/HotChocolate/Core/test/Types.Tests/Resolvers/IsSelectedTests.cs	Adds regression test that previously would trigger a KeyNotFoundException when the pattern was declared on a non-Query type.
src/HotChocolate/Core/test/Types.Tests/Resolvers/snapshots/IsSelectedTests.IsSelected_Pattern_On_NonQueryType_Should_Build_Schema.md	Snapshot for the new regression test output.
