[PM-40569] UI layout breaks when iOS Accessibility "Show Borders" is enabled (It's not server related, it's a client issue.)

### Steps To Reproduce

The problem is with the phone app (client) and not with the server.

On iPhone running iOS 26.5.2, open:
Settings → Accessibility → Display & Text Size.
Enable "Show Borders".
Open Bitwarden.
Observe list items.

### Expected Result

I expect the elements to look normal.

### Actual Result

The control elements take up more space, have a gray background and a rounded border, and the color of the icons changes to blue.

### Issue Tracking Info

- [ ] I understand that work is tracked outside of Github. A PR will be linked to this issue should one be opened to address it, but Bitwarden doesn't use fields like "assigned", "milestone", or "project" to track progress.

Reproduce the issue in the Bitwarden iOS app on an iPhone with Settings → Accessibility → Display & Text Size → Show Borders enabled, then inspect the affected list items and controls. Done means the controls retain their normal size, background, borders, and icon colors while Show Borders remains enabled.
