User carts and workflow UI refresh

Moving material through the lab is now easier to organize and easier to see. This release adds personal carts for active work and refreshes key screens so teams can move faster with fewer clicks.

Personal carts for in-transit work

You can now keep items in named carts while you are actively working.

Create multiple carts for different runs (for example, initiation vs subculture)
Set one active cart so newly scanned items go to the right place
Rename carts as your day changes
Remove empty carts you no longer need

Better task flow from cart to workstation

Tasks and carts now work together more naturally during real lab workflows.

Load tasks onto a cart so all related items stay grouped
See tasks associated with the current cart while scanning
Move items from cart to workstation or storage in fewer steps
Keep better chain-of-custody visibility while items are in transit

Cleaner pages and updated navigation

Several areas were reorganized to make common actions easier to find.

“My Cart” now appears where teams expect it in core workflow views
Catalog and inventory labels were cleaned up for clearer navigation
Reusable list and toolbar patterns were introduced across multiple screens
Settings and operations pages received consistency updates for layout and controls

What this means for your team

Less confusion about where items are during handoffs
Faster scan-to-action workflows on busy days
Better separation of parallel runs for each technician
A more consistent interface across app sections

Technical details (for power users)

User trays were refactored into a multi-cart model with one active cart per user.
New cart endpoints support create, activate, rename, delete, claim by code, and task association.
Scan actions (check_out, collect) route through the active cart via getActiveCartOrCreate.
Existing data can be migrated to carts using the migration utility script.
