refactor: integrate export records into project details page

- Add export records tab to ProjectDetails page
- Optimize ExportRecordManager for compact tab display
- Remove global export records navigation (now project-level)
- Add showHeader and compact props to ExportRecordManager
- Remove standalone ExportRecordsPage (no longer needed)
- Update navigation structure to reflect project-level functionality

Export records are now properly scoped to individual projects and accessible through the project details interface.
