Faster UI

Frontend: 
- Remove Aladin loading from every page. Only include it for pages that actually use Aladin.

Backend: 
- Reduce number of SQL requests to DB in favour of JOINs. `table_id` -> `table_name` in particular.
- Run all network requests (to ADS/DB) in parallel. Maybe write some parallelization framework so the calls are similar to Go's `go func() {}` or `errgroup`
