Sprint 20. Adds features/admin/categories/ (model, gateway interface +
local gateway, facade, list/editor pages), mirroring the admin/products
container/facade/service split.
- indented hierarchy view + native HTML5 drag-and-drop reorder
- visibility toggle, item counter, empty state, include-deleted filter
- editor: slug uniqueness validation, translations, SEO fields, breadcrumb
preview, image via existing MediaPickerComponent
- soft delete/restore, blocked when a category has children or items
- draft/publish status + localStorage draft recovery (mirrors Project
Editor autosave) + CanDeactivate unsaved-changes guard
- wired into app.routes.ts (replaces the categories coming-soon placeholder)
- docs/ADMIN.md + docs/BACKEND.md updated with the new gap detail
Not yet done: admin/products' category dropdown still reads from its own
AdminProductsGateway.loadCategories() rather than this gateway (Sprint 21).

Replace single-line text/number inputs with app-form-field/app-input across
name, slug, sku, brand, priority, pricing, quantity, availability, per-locale
translation name/shortDescription, SEO metaTitle/keywords, and badges fields.
Save button now app-button. Textareas, selects, and checkboxes stay native -
no Textarea/Select/Checkbox primitive exists yet. Added app-form-field.full
grid-column rule alongside the existing label.full one (custom element,
different selector).
Production build green, arch:check passes.
Replace raw button/table/input elements with app-button, app-table, app-badge,
app-input, app-pagination. Removed now-redundant button/table/th/td CSS from
the stylesheet (would have double-styled the primitives' projected content
under Angular's emulated encapsulation). Native selects and checkboxes kept
as-is - no Select/Checkbox primitive exists yet.
Production build green, arch:check passes. In-browser verification hit a
dev-server routing hiccup unrelated to these changes (a temporary unguarded
preview route 404'd despite compiling correctly); relied on the identical,
already-verified primitive usage pattern from the Static Pages editor and
Media Manager instead.
