Fix /api/v1/event/token/{uuid} not checking workflow states

[nscuro]

Description

Fixes /api/v1/event/{token} not checking workflow states.

/api/v1/bom/{token} was deprecated in v4.11 and removed in #910.

Since BOM upload progress is tracked in durable workflows in v5, the new event endpoint must be adapted to check those as well.
