fix(neuphonic): pass WebSocket TTS API key via header

[rosetta-livekit-bot]

Description

Both livekit-plugins-neuphonic and livekit-plugins-murf were embedding the API key in the WebSocket URL query string without URL-encoding. Move the key onto the WS handshake header instead — both providers' SDKs/docs already support header auth.

Changes

• neuphonic: drop api_key= from the WS URL; the existing X-API-KEY header was already redundantly set on the handshake. JWT-token URL handling is unchanged.
• murf: switch from the ?api-key=... query param to the api-key header (matches Murf's official Python SDK and WS API reference).

Testing

• make check (ruff lint + format-check) passes locally on both edited files.
