Add aria-label attributes to all icon-only buttons in admin package

[mighty840]

Description

The entire admin package contains no ARIA attributes. Every icon-only button is inaccessible to screen reader users. This includes buttons across Dashboard, KitchenDisplay, OrderDetail, StaffList, MenuItemForm, and Settings pages.

Examples

• Refresh button in KitchenDisplay (line 163) — icon-only, no label
• Status update buttons in KitchenDisplay (lines 282–304)
• Cancel order button in KitchenDisplay (line 300)
• Edit/delete buttons across list views

Requirements

1. Audit all admin pages for icon-only buttons and interactive elements
2. Add descriptive aria-label attributes to each
3. Use translation keys where the admin has i18n set up, or plain English as a starting point

Effort

M — touches many files but each change is simple

Hi! I'd love to take this on. I will audit the admin pages and add the missing aria-label attributes to all icon-only buttons to make them screen-reader friendly. I'll also make sure to use the proper i18n translation keys where available. Could you assign this to me?
