perf(keyboard): track KeyboardState per property with @Observable

- KeyboardState moves from ObservableObject/@Published to @Observable, so a view re-renders only for the properties it reads. Previously unpublished state and injected action hooks are @ObservationIgnored. - KeyboardViewController replaces the $phase/$surface Combine sinks with Observations loops tied to the same cancellables. - AIKeyboardView reads the 200 ms mic level and live ASR partials in small child views (AssistantWaveform, LiveTranscriptReader), so those ticks no longer rebuild the whole assistant surface. - Tests observe changes with withObservationTracking instead of Combine publishers.
