fix: sync/barcode/memory overhaul + detailed logs + preview + result tracking

- Sync: fix GiteaSync constructor + add push()/pull() methods
- Barcode: two-tab layout matching GUI (mapping + special rules)
- Memory: spec→specification unification, manual add, confidence/price tracking
- Processing: TaskLogHandler captures detailed logs (barcode mapping, unit conversion)
- Preview: fullscreen dialog for file preview (image/Excel) in Orders/Tables/Images
- Detail: per-file log filtering in file pages
- Tasks: result files now per-task, add copy path button
- Config: reactive edited state + save_config fix
- Dashboard: sync task isolation, log limit 10
