Replace every hardcoded English string across all 35 SPA page files
with useT() calls backed by message keys in messages.ts. Both en-US
and zh-CN translations are provided for every key (~200 new keys).

Pages updated: DashboardPage, LoginPage, FormDesignerPage,
ListViewDesignerPage, MetadataAdminPage, SalesOrderDetailPage,
PurchaseOrderDetailPage, WorkOrderDetailPage, ShopFloorPage,
UserTasksPage, TaskDetailPage, UserDetailPage, all Create* pages,
all Edit* pages, and all list pages (Items, Partners, Locations,
Balances, Movements, SalesOrders, PurchaseOrders, WorkOrders,
Users, Roles, Accounts, JournalEntries, UoMs, AdjustStock).

When type is 'enum', show a comma-separated input for allowed values.
When type is 'string', show a max-length input. Previously these
type-specific options were missing from the UI.
