Neue Tabelle config_overrides in SQLite; RuntimeSettings-Wrapper liest
überschreibbare Felder mit 30s TTL-Cache aus der DB und fällt auf
.env-Werte zurück. dependencies.py und quota.py nutzen runtime_settings
als Default statt des statischen Settings-Singletons.
16 Felder überschreibbar: STT/LLM/TTS-Provider, LLM-Modelle, Stimmen,
Systemprompt, Temperatur, Tageskontingent, Normalisierung u.a.
Backend: GET/PUT/DELETE /api/admin/config/{key}
Admin-UI: neuer Tab "⚙ Einstellungen" mit Inline-Edit und Reset.

"""Laufzeit-Konfigurationsüberschreibungen aus der Datenbank.

|

Einzelne Settings-Felder können zur Laufzeit via Admin-UI geändert werden,
|
||
ohne den Server neu zu starten. Die Werte liegen in der Tabelle
|
||
`config_overrides` und werden mit 30s TTL gecacht.
|
||
|
||
Nur Felder aus RUNTIME_SETTABLE sind überschreibbar — alle anderen
|
||
kommen weiterhin aus .env / TOML / pydantic-settings.
