Add step logging functionality to ProgressModal and useProgressModal

- Introduced stepLogs to ProgressModal and useProgressModal for enhanced debugging.
- Updated ProgressModal to display step logs with status indicators.
- Modified useProgressModal to manage step logs, collecting and sorting steps from AI requests.
- Adjusted Clusters and Ideas pages to pass stepLogs to ProgressModal for improved user feedback during asynchronous tasks.
- Fixed a typo in Usage.tsx header for clarity.
