Add an endBeforeStart $derived to WhoWhenSection (lexicographic ISO compare, no Date object) that renders an inline error on the end-date field — border-red-400, aria-invalid, aria-describedby, and a #end-date-error <p> inside the existing aria-live region — with a ⚠ glyph so the cue is not colour-alone (WCAG 1.4.1). Save is not disabled; the server stays the gate. Wire ErrorCode INVALID_DATE_RANGE through errors.ts getErrorMessage and add the single key error_invalid_date_range to de/en/es, so the same translated string is used inline (client) and via getErrorMessage (server fallback).
