- Add category image API methods (upload/delete) to src/api/index.js
- Add uploadCategoryImage/deleteCategoryImage thunks and extraReducers in categorySlice
- Add CategoryBackdrop component showing ThumbHash placeholder with full thumb overlay
- Add photo upload/delete tab to CategoryEditTile settings cycle
- Category tile label band uses semi-transparent black overlay with white text
- Pass thumbHash/fullHash to both CategoryTile and CategoryEditTile
After toggling a POS category, update the category's posterminalIds array
in-place rather than re-fetching the entire tree. This keeps the settings
cycle open on the same terminal. Also fix off-by-one in terminal cycling
and ensure posterminals load on category page mount.
- Edit toggle behind the "Kategorien" title enables an edit mode.
- In edit mode all category tiles become inline rename fields (no outline,
distinct background, small margins); articles and "new article" are hidden.
- Rename via PATCH /api/category/:id; reorder via PUT /api/category/order
(parentId + categoryIds) with SortableJS.
- Only call backend when order actually changed; revert DOM order on error
so further dragging keeps working.
- Redux: renameCategory + reorderCategories thunks, renameMode state.
