- createEmptyDocument now uploads a minimal PDF so the Transkribieren
button is rendered (requires isPdf = true in DocumentTopBar)
- add 'Transcribe coach — with blocks' describe: seeds a block via API,
waits for blocks to settle in read mode, switches to edit, confirms
'Für Training vormerken' is visible
- fix dark-theme axe test: ThemeToggle uses aria-label 'dark mode',
not the previous /Farbmodus|theme/ regex
