Add keyboard accessibility to the sell key modal so all actions are reachable without a mouse

[Chucks1093]

Summary

The sell key modal cannot be fully operated via keyboard — focus is not trapped and pressing Escape does not close it. Fixing this makes the feature accessible to keyboard-only and assistive technology users.

Scope

• Trap focus inside the modal while it is open (Tab and Shift+Tab cycle within)
• Set initial focus on the quantity input when the modal opens
• Pressing Escape closes the modal
• The confirm button is reachable via Tab and activatable via Enter or Space
• Return focus to the trigger button when the modal closes

Acceptance Criteria

• Focus trapped inside the modal while open
• Initial focus lands on the quantity input
• Escape closes the modal
• Confirm button activatable via keyboard
• Focus returned to trigger button on close

ETA: 12 hours
