List all flex controls grouped by program, with pagination support. Results are ordered by program ID in ascending order.
Use the optional programId query parameter to filter results to a single program.
If programId is provided and no templates are found for that program, a 404 is returned.
If no programId is specified and no templates exist at all, an empty paginated response is returned with status 200.
