feat(analytics): eventos GA4 audio_play y share_click

fea-audio-player.php: el <audio> lleva data-post-id/data-voice; listener
en wp_footer dispara gtag('event','audio_play', {post_id, voice}) en el
primer play (no en cada resume).

fea-share.php: se sube también al repo (nunca se había comiteado). El
botón de Facebook lleva data-fea-share-track="facebook" + listener que
dispara gtag('event','share_click', {method, post_id}).

Ambos reusan el dataLayer/gtag que ya inicializa fea-analytics.php, sin
añadir JS de terceros. Verificado en local con Playwright (evento se
dispara correctamente en ambos casos).
