feat: EOL API pagination

[rlmestre]

Closes neverendingsupport/data-and-integrations#262

[Copilot]

Pull Request Overview

This PR implements pagination for the EOL API to handle large reports by fetching components in pages rather than all at once. The changes include new GraphQL operations for paginated data retrieval, configuration for page size and concurrent requests, and updated mocks to support the new paginated flow.

• Refactored EOL report creation to return only metadata and total record count
• Added paginated fetching of report components with configurable page size and concurrent requests
• Updated all tests and mocks to support the new two-step report creation and retrieval process
