Bot hang fix for tool calls with incomplete user turns

Full Release Notes

### Changed

- Changed the default WebSocket endpoints for `GradiumSTTService` and `GradiumTTSService` to the region-neutral `wss://api.gradium.ai/api/speech/asr` and `wss://api.gradium.ai/api/speech/tts`. Gradium now automatically routes traffic to the nearest endpoint. Override the url to pin to a specific region.

### Fixed

- Fixed bot hangs when `filter_incomplete_user_turns` was enabled and the LLM responded by calling a tool. The user turn never finalized, so the assistant aggregator gated the tool-result context push and the LLM continuation never ran. Tool calls now finalize the turn the moment they start, before the function dispatches.
