refactor: explicit kind=='final' check in async-tool routing (Gemini Live)

Browse Source 
Mirrors the same change applied to AWSNovaSonicLLMService and
OpenAIRealtimeLLMService in #4441 / GrokRealtimeLLMService in #4447:
replaces the implicit "final happens last" pattern in
_process_completed_function_calls with an explicit
`if async_payload.kind == "final":` block, plus a trailing defensive
`continue` so async-tool messages with an unrecognized kind don't fall
through to the regular tool-result handling block.
