shrey kharbanda 363cc0da04 fix(passthrough): bill a WebSocket session whose client hangs up mid-stream
When a client closed its socket while the upstream was still sending, the
relay's next send to the client raised, the session took the unexpected
error path, the client got a 1011 close and the proxy wrote a failure row
with no cost. The upstream had already done, and billed, the work

A send to a client that has gone now ends the session the way a client
disconnect does: the upstream is closed, the frames received so far reach
the success handler and spend is logged once. Each upstream frame is
recorded before it is sent, so the frame whose send failed is billed too.
For Deepgram listen that can be the closing Metadata frame, which carries
the session's duration. Starlette raises WebSocketDisconnect when the
socket fails and uvicorn raises RuntimeError once the transport is closed,
so both count as the client leaving

Every WebSocket passthrough (Deepgram listen, Vertex Live, realtime) shares
this relay. Text-to-speech makes it common, since callers hang up or barge
in while audio is still streaming
