fix vocab pronunciation-task validity detection

[koljapluemer]

this is of course utter garbage:

    const withoutPronunciation = vocab.filter(vocab => {
      // Since pronunciation is now handled as notes, we'll check for pronunciation notes
      // For now, assume all vocab needs pronunciation (to be refined later)
      const hasNoPronunciation = true; // TODO: Check if vocab has pronunciation notes

and we can't pass the note repo into this, so we probably need to rename and use notInterestedInPronunciation
