fix: reject misrouted smallwebrtc runs on the telephony websocket (#468)

* fix: reject misrouted smallwebrtc runs on the telephony websocket

A smallwebrtc (browser/WebRTC) workflow run is established through the WebRTC
signaling endpoint, not the PSTN telephony websocket. When such a run reached
_handle_telephony_websocket it read no "provider" from initial_context and
closed with an opaque "Provider type not found". Detect smallwebrtc runs and
close with a clear reason pointing to the signaling endpoint, without setting
the run to running or invoking a telephony provider. Also store the provider on
smallwebrtc runs at creation so they are self-describing, and make the generic
no-provider close reason include the run id and mode.

Closes #433

* fix: merge workflow run initial context defaults
