Push this backend's tools and prompt onto the live Vapi assistant
The assistant's tools and system prompt live on Vapi's platform, not in this backend - adding a tool here (e.g. navigate_page) does nothing to the assistant Vapi actually runs until it is pushed there. This does that: it fetches the configured assistant, replaces its system message and tool list with this backend's VOICE_TOOLS and SYSTEM_PROMPT, and leaves its provider, model and voice untouched. Runs automatically at startup; call it again after editing a voice tool without restarting the server.

Returns the public key, assistant id and per-session overrides the browser SDK needs. Includes a short-lived session token that the assistant presents when calling back into the API, so voice tool calls are authenticated and merchant-scoped like any other request.
Run one voice tool directly POST
Executes a single tool against the same registry the web agents use. Authenticated with the short-lived voice session token; never anonymous.
