Add missing base components and global alias registrations

Create BaseCustomTag (dynamic tag render), BaseFormatMoney,
BaseHeading, BaseScrollPane, BaseDescriptionList/Item, BaseLabel,
BaseCustomerSelectInput, BaseSpinner, BaseRating, and status label
components. Register all renamed v2 components under their old
Base* names (BaseInputGroup->FormGroup, BasePage->Page,
BaseTable->DataTable, etc.) so templates resolve correctly.
