add conditional warning for destructive delete operation

- Added React state to track toggle status and show warning only when enabled
- Implemented modern custom border warning style with left red border and subtle background
- Added responsive width constraints (max-w-[24rem]) and word wrapping for proper layout
- Warning includes ⚠️ emoji and clear messaging about irreversible operation
- Fixed JSON syntax errors in translation files (replaced HTML entities with escaped quotes)
- Enhanced translations: "Also delete" phrasing and detailed warning messages
- Warning appears dynamically when bulk deletion option is activated
