Vocab Practice — speaker button to hear the Spanish word

Both vocab session reveal panes now show a speaker button next to the
Spanish infinitive. Tapping it speaks the word via the existing
SpeechService (Spanish voice), same TTS the Course flashcards use.

Flashcard mode: button beside the infinitive in the reveal pane.
Multiple choice: button beside the infinitive in the answer feedback.
