feat: add throwable support to Log.d/i and inline lambda overloads

- Add optional throwable parameter to d() and i() across all platforms
- Add inline lambda overloads for all log levels to defer message
  construction, avoiding string allocation when level is filtered
- Restore VoiceMessagePreview to pass throwable directly
