POS screen redesign

Please update the POS screen top header menu icon layout. The current design is too large and limits future scalability. As more menus or options are added, it won’t be efficient.

Right now, the design supports only a few icons and consumes more space. Instead, adopt a cleaner approach with square-style icons and a flat header layout. This will allow more items to fit while keeping the interface neat and scalable.

No need to use the same colors—just follow a similar icon structure and layout style.
