* Review

- "grocy" is currently written lower-case everywhere, so let's do this also for "grocycode"
- Unified phrases / capitalization
- Minor UI adjustments (mainly context menu item ordering / ordering/spacing on product edit page)
- Documented API changes for Swagger UI (grocy.openapi.json)
- Reverted German localizations (those are managed via Transifex; would cause conflicts when manually edited - will import them later there)
- Reverted a somehow messed up localization string (productform/help text for `cumulate_min_stock_amount_of_sub_products`)
- Suppress deprecation warnings when generating Datamatrix PNG (otherwise the PNG is invalid, https://github.com/jucksearm/php-barcode/issues/3)
- Default `FEATURE_FLAG_LABELPRINTER` to disabled
