[BUG] [a11y] Create Project stepper buttons not fully visible at 200% text resize

## Description

At 200% text resize, the Create Project page step buttons (e.g., Access, Review) are not fully visible, making it difficult for low-vision users to see or interact with step navigation controls.

## Environment

- AKS Desktop Version: 0.1.0-alpha
- Headlamp Version: 0.38.0
- OS: Windows 11 Enterprise version 24H2 (Build 26567.1000)
- Display Resolution: 1280x768
- Text Size: 200% (Settings > Accessibility > Text Size)

## Repro Steps

1. Set display resolution to 1280x768
2. Set text size to 200% (Settings > Accessibility > Text Size)
3. Launch AKS Desktop and log in
4. Navigate to Home > Projects tab
5. Click "Create Project" > "AKS Managed Project"
6. Observe the stepper buttons (Access, Review) on the New Project page

## Actual Behavior

At 200% resize, Create Project page step buttons (Access, Review) are not fully visible.

## Expected Behavior

At 200% resize, all step buttons should remain fully visible, readable, and reachable without loss of content or functionality.

## User Impact

Low-vision users who rely on text resizing cannot clearly see or interact with step navigation controls, making it difficult to understand progress or navigate between steps in the Create Project flow.

## MAS Reference

MAS 1.4.4 – Resize Text

Reproduce the issue in AKS Desktop on Windows 11 at 1280x768 with 200% text size, following the listed Home > Projects > Create Project > AKS Managed Project steps. Inspect the New Project stepper containing Access and Review, and verify that all buttons remain fully visible, readable, and reachable without loss of functionality.
