- Add bulk_drop_desc, bulk_select_files, bulk_drop_zone_label, bulk_remove_file
keys to de/en/es message files
- BulkDropZone: use m.bulk_drop_zone_label(), m.bulk_drop_desc(),
m.bulk_select_files() — removes all hardcoded German
- FileSwitcherStrip: use m.bulk_remove_file() on × button; move aria-live
from <ul> to a dedicated visually-hidden region above the strip (screen
readers now announce changes without coupling the live region to the list)
- Spec: import FileEntry from component instead of re-declaring; use
data-remove-id selector instead of hardcoded German aria-label
