Describe the bug
In Admin Panel → Settings → Audio, both STT and TTS engine dropdowns are missing most backend-supported options:

STT only shows: Default, Web API
TTS only shows: Default, Kokoro.js (Browser)

Backend router (audio.py) supports openai, azure, deepgram, mistral for STT and openai, azure, elevenlabs for TTS — none of these appear in the UI.

This is confirmed as a frontend-only issue: after manually writing audio.stt.engine=openai + API key directly into the config table in webui.db, OpenAI Whisper transcription works perfectly (backend logs show POST /api/v1/audio/transcriptions → 200). The dropdown still does not reflect the active engine.

Steps to reproduce

docker run -d --name open-webui -p 4319:8080 -v open-webui-data:/app/backend/data ghcr.io/open-webui/open-webui:main
Log in as admin
Admin Panel → Settings → Audio
Click STT Engine dropdown — only Default / Web API
Click TTS Engine dropdown — only Default / Kokoro.js (Browser)

Expected behavior
Dropdowns should list all engines supported by the backend: OpenAI, Azure, Deepgram, Mistral (STT) and OpenAI, Azure, ElevenLabs (TTS).

Workaround
Directly insert config into webui.db:

# inside container
import sqlite3, json
conn = sqlite3.connect('/app/backend/data/webui.db')
row = conn.execute('SELECT data FROM config WHERE id=1').fetchone()
data = json.loads(row[0])
data['audio.stt.engine'] = 'openai'
data['audio.stt.openai.api_base_url'] = 'https://api.openai.com/v1'
data['audio.stt.openai.api_key'] = 'sk-...'
data['audio.stt.model'] = 'whisper-1'
conn.execute('UPDATE config SET data=? WHERE id=1', (json.dumps(data),))
conn.commit()

Then restart container. Backend works; UI still shows wrong engine name.
