Studio: add clone-all-per-hotel, per-item status detail, retry, ETA, and auto-translate

- Add 'Clone all missing' button for clone sources with confirmation dialog
- Show per-item status badges: nitro, furnidata, catalog entry
- Add status filters: missing furnidata, missing catalog entry
- Add ETA and percentage to batch progress bar
- Add retry button for failed items after batch import
- Auto-translate all languages after clone-all completes
- Fix statusFilter 'all' bug that incorrectly filtered imported items
- Bulk-load FurnitureData + catalog references for O(1) per-item checks
