[Bug]: App zoom ignores numpad keys and Ctrl+mouse-wheel

Before submitting

• I searched existing issues and did not find a duplicate. The closest report, #2706, concerns configurable shortcuts and non-US keyboard layouts, not numpad keys or mouse-wheel zoom.
• I included enough detail to reproduce or investigate the problem.

Area

apps/desktop

Steps to reproduce

1. Open T3 Code desktop on Windows.
2. Hold Ctrl and press + or - on the numeric keypad.
3. Hold Ctrl and scroll the mouse wheel.
4. For comparison, press Ctrl with + or - on the keyboard's number row.

Expected behavior

The numeric-keypad shortcuts and Ctrl+mouse-wheel should change the application zoom, matching the number-row shortcuts. These are common zoom inputs in Windows desktop applications and browsers.

Actual behavior

Ctrl+numpad +, Ctrl+numpad -, and Ctrl+mouse-wheel do nothing. Only Ctrl with the number-row + or - changes the application zoom. Because the font-size settings do not scale every UI element, this makes application zoom difficult to discover and led me to assume that T3 Code had no whole-interface zoom.

Impact

Minor bug or occasional failure

Version or commit

Desktop 0.0.38

Environment

Windows 11 Pro, T3 Code desktop x64

Logs or stack traces

None.

Workaround

Use Ctrl with + or - on the keyboard's number row.

Start in the apps/desktop area and trace how the application handles Ctrl with number-row zoom shortcuts. Reproduce the issue on Windows 11 with Ctrl+numpad +/-, Ctrl+mouse-wheel, and the existing number-row shortcuts; done means all three input forms change application zoom consistently.
