feat: optimize export data structure and UI display

- Simplify export data by removing filesRead stat, keep only written files count and paths
- Restore lines-related statistics (linesAdded and linesRemoved)
- Update HTML display to show only file operation stats instead of total files count
- Change 'Written' label to 'Files modified'
- Remove distinction between requestId and sessionId, always display sessionId
- Remove Session ID and Export Time from Header (already shown in MetadataSidebar)
- Display Project field with raw value and support multiline display
- Fix filesWritten calculation to count unique files instead of operations
