Windows: Button keyboard shortcut hints show macOS icons instead of Windows equivalents

Description

On Windows, all buttons that display keyboard shortcut hints show macOS-style modifier key icons instead of the correct Windows equivalents.

Examples observed:

• "Allow once" button shows ⌘⇧↵ instead of Ctrl+Shift+Enter
• "Always allow" button shows ⌘↵ instead of Ctrl+Enter
• "Revise" button (shown after a plan completes) exhibits the same issue

This affects all shortcut-annotated buttons throughout the app — it is not limited to a specific view or action.

Steps to Reproduce

1. Open Claude Desktop on Windows
2. Trigger any prompt that shows action buttons with keyboard shortcut hints (e.g. a tool permission dialog, or finish a plan to see the "Revise" button)
3. Observe the keyboard shortcut icons displayed alongside the button labels

Expected Behavior

Shortcut hints should use Windows-appropriate key symbols:

• Ctrl instead of ⌘
• Shift instead of ⇧
• Enter instead of ↵ (or keep the arrow, but pair it with Ctrl/Shift labels)

Actual Behavior

macOS Command (⌘) and Shift (⇧) glyphs are shown verbatim on Windows, where these keys do not exist.
