1. API: Pagination for forecasts
2. Frontend: Paginate the table of forecasts
3. cleoc: Paginate the list of forecasts

Having all forecasts being displayed in one table stops being feasible after ~100. The ability to paginate is a must. I find Continuous Scrolling rather annoying in practice and in particular with these types of applications where you do want a sense of how many items there are it is not helpful.
