fix: sort category lists alphabetically on the Categories page

Expense/income lists were rendered in server sort_order (chart palette
slot order), which looks arbitrary for browsing/managing categories.
Sorts by translated name instead, locale-aware — same approach
BudgetFormModal's category picker already uses. Display-only; sort_order
itself is untouched since the dashboard donut chart still relies on it.
