Original PR description:

Issue

The "Get Certificate" and "Update Certificate" buttons in DeviceDetailsButtonsView have a tap area limited to the text width, making them difficult to tap.

Cause

The button labels were not configured to expand to the full row width, so only the text itself was interactive.

Solution

Wrap each button label in an HStack with a Spacer, set .frame(maxWidth: .infinity), and apply .contentShape(Rectangle()) to make the full row area tappable.

Testing

1. Open device details for a device eligible for E2EI certificate enrollment or update
2. Tap to the right of the certificate button text
3. Verify the button action triggers
