[GEN-2170]: implement paginated sources for improved performance

[BenElferink]

This pull request includes changes to the GraphQL schema and resolver logic to introduce pagination for the sources field in the ComputePlatform type. The primary changes involve replacing the existing K8sActualSources field with a new PaginatedSources type that supports pagination.

Changes to the GraphQL schema:

• frontend/gqlgen.yml: Added resolver: true for the new sources field.
• frontend/graph/schema.graphqls: Replaced k8sActualSources with sources that returns PaginatedSources, which includes nextPage and items fields. [1] [2]

Changes to the resolver logic:

• frontend/graph/schema.resolvers.go: Updated the resolver for the sources field to handle pagination using nextPage parameter and return PaginatedSources.

Changes to the generated code:

• frontend/graph/generated.go: Updated complexity functions, field arguments, and resolver middleware to support the new PaginatedSources type and handle pagination logic. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15]

Changes to the model definitions:

• frontend/graph/model/models_gen.go: Added the PaginatedSources type and updated ComputePlatform to use PaginatedSources for the sources field. [1] [2]
