feat(smus): Add status validation for space operations

**Description**

Added status checks for SageMaker space operations to prevent invalid actions.

**fix done**

1. The stopSpace function now validates space status before attempting to stop, showing appropriate warning messages for spaces already in Stopped/Stopping states or currently Starting.

2. Also added status refresh before open remote connect

**Testing Done**
