List evidence for an information request

Retrieves a paginated list of all evidence attached to an information request, enabling auditors to review evidence submitted by customers.

This endpoint always includes soft-deleted records (where deletionDate !== null). Clients should check the deletionDate field to identify and handle deleted records appropriately in their systems.

This endpoint supports delta synchronization via the changedSinceDate parameter, allowing efficient polling for changes without retrieving the entire dataset.

Pagination usage:

1. Make initial request with desired pageSize
2. Check results.pageInfo.hasNextPage to see if more data exists
3. If true, use results.pageInfo.endCursor as pageCursor in next request
4. Repeat until hasNextPage is false

Delta sync usage:

1. Store the timestamp of your last sync
2. Pass that timestamp as changedSinceDate
3. Only evidence created, modified, shared, or deleted since that timestamp is returned
4. Process updates, including soft-deletes (deletionDate !== null)
5. Update your last sync timestamp to the current time
