Reconcile website_* schema to the live AtomCMS DB (amx_test)

Introspected the live DB and fixed real drift between the hand-modeled
schema and the actual columns:
- Added missing @map("snake_case") on camelCase fields that silently
  failed at query time: website_teams (rank_name/hidden_rank/...),
  website_paypal_transactions/user_guestbooks/help_center_tickets(+replies)/
  used_shop_vouchers/maintenance_tasks (user_id), website_rare_values
  (currency_type).
- website_permissions was modeled as key/value/comment but is actually
  permission/min_rank/description — fixed the model + the admin page/action.
- website_shop_articles.icon -> icon_url (+ added category_id, is_giftable);
  updated the shop page + admin shop CRUD.
- website_shop_categories: dropped non-existent slug/timestamps, added the
  real description/order columns; updated the shop page.
- website_shop_article_features.features(Json) -> content(Text).

Verified against amx_test: all website_* query errors gone; home renders
the real hotel_name ("Habbo"), rankings shows real users, /staff + /shop
200. tsc 0, vitest 49/49, next build 0. Remaining missing tables
(radio_*/game_*/staff_activities/alert_logs/article_comments+reactions)
don't exist in this DB and degrade gracefully via try/catch.
