fix(knowledgeBase): improve navigation and folder tree refresh logic

- Add path comparison check in breadcrumb navigation to avoid unnecessary route changes when already on target page
- Implement delayed folder tree refresh with setTimeout to ensure state reset completes before refreshing
- Add manual table refresh trigger to ensure data updates after navigation
- Reset expanded keys in FolderTree component during load to ensure consistent state from root directory
- Add expanded keys reset in breadcrumb navigation to prevent stale expansion state
- Improve navigation state handling by using replace flag only when on target path to reduce history stack pollution
