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.
Updated the SettingsProfileHeader widget to use a lighter background, reduced the expanded height, and adjusted layout to a horizontal row with updated avatar and text styles. Added new spacing constants to UiConstants for improved layout control.
Relocated all app directories (client, design_system_viewer, staff) and their contents under the new 'apps/mobile' path. This change improves project organization and prepares for future platform-specific structuring.
