Subject: [PATCH] fix: Voice-Stop greift hart durch + Schriftgroesse wirkt
 jetzt im Chat [appimage]
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Voice-Stop:
- TTS-Audio jetzt vollstaendig zerstoert (pause + src='' + load) statt nur pause
- Wartende speakAndWait()-Promise wird beim Stop aufgeloest (vorher Hang)
- isActive()-Check direkt nach text_to_speech Result, kein Audio-Start mehr nach Stop

Schriftgroesse:
- .content hatte feste 13.5px → ueberschrieb --chat-font-size
- Headings (h1-h3) hatten feste px-Werte → jetzt em (relativ zu User-Schrift)
