Restore recommended sentence + language switcher to Clone a Voice

Adds the 'Read aloud' sample-sentence box back to the microphone card
in the Clone a Voice tab. Language switcher covers EN/DE/IT/ES/FR/PT/NL/PL
with phonetically diverse sentences (same as the My Voices panel).
Uses the existing .sample-read-box / .sample-sentence CSS so it looks
identical to the equivalent panel in the voice library.
