feat: add dynamic header navigation with current page tracking

- Added useLocation hook to detect and display current page in header dropdown
- Extracted cloud navigation items into separate constant for reusability
- Implemented getCurrentPageName function to determine active page based on URL path
- Updated dropdown button to dynamically show current section instead of static "Cloud" text
