Fold the medication API tab back into Erweitert

Seven tabs on a medication cut the strip off mid-label at 390 px. The
API tab's one group (per-medication tokens and drug coding) now sits in
Erweitert as a collapsed group before the danger zone, an old ?tab=api
link lands there, and on a phone the six remaining tabs wrap into two
rows instead of scrolling a label off the edge.
