fix(web): begivenhederne i en celle sorteres, hvor de tegnes

Serveren sorterer allerede, men en celle, der viser 14:00 over 09:15, ligner
ikke en liste i forkert rækkefølge — den ligner et forkert klokkeslæt på
chippen, og det er langt værre at skulle udelukke. Heldags først: en heldags
begivenhed er et bånd hen over dagen, ikke noget der sker på et punkt i den.
