scoring-event.ts exported getEventTypeLabel, a pure display helper used
directly in route components, from the same module that imports
scoring-calculator.ts (which now pulls in the Discord notification
service, a .server-only module). Because that whole chain was
value-imported into the client bundle, Vite's server-only-module guard
failed the build. Move getEventTypeLabel into a new client-safe
scoring-event-types.ts module with no server dependencies, and import
it directly where it's rendered.
