🐛 fix(message): ensure retry uses current selected model instead of stale one

- Add onMessageReset reference comparison to OptimizedMessageActions memo
- Force component re-render when model selection changes
- Prevent stale closure issue in retry functionality
- Ensure first retry attempt uses newly selected model

Previously, when changing the model selection, the retry button would
still use the previous model due to React memo optimization preventing
re-renders. By comparing the onMessageReset callback reference, the
component now properly updates when the model changes, ensuring the
retry functionality immediately uses the currently selected model.
