fix(tts): lower base speed 1.5→1.2 — 1.5x slurred Korean pronunciation

Browse Source 
User reported the 1.5x base made Korean pronunciation mushy/slurred. Dial the
default WSAI_TTS_SPEED back to 1.2: still noticeably faster than the original
1.0, but clear. Emotion multipliers scale off base as before.
