Item Code Search to select Items for Picking, Repacking, Unpacking, Container Loading, etc.

Introduce a search field for the item selection process during operations such as:
- picking,
- repacking,
- unpacking,
- removing,
- printing labels
- setting locations
- container loading/unloading,
placed above the bottom navigation bar and below the item cards. This feature will allow users to quickly filter and locate items by typing in the item code. This enhancement provides an alternative method for users who cannot use the scanner due to issues or prefer not to scroll through long lists.
