Add order entities and mocks for client order feature

Introduces new domain entities for order types and one-time orders, along with their positions. Adds a mock OrderRepository to the data_connect package and wires it into the module. Updates localization files for new order flows and refactors Equatable usage for consistency. Also adds a minus icon to the design system.
