[UEPR-624] Make sure focus outline is visible on Safari

Resolves

UEPR-624

Proposed Changes

Ensure components with overflow: hidden do not cut off the focus outline in Safari.

• Tutorial Cards: Added sufficient padding to ensure the focus outline renders completely. Also added outline-offset to reduce the spacing required for the outline to appear.
• Debug Modal: Removed unnecessary padding that caused the button to overflow its parent component and distort the outline shape.
• Settings Submenus: Removed overflow: hidden from the Theme and Color Mode menus, as they contain only a few elements and do not require it. The Language menu retains overflow: hidden because it requires a max-height and a scrollbar, which inherently changes how Safari renders its outlines and prevents them from being clipped.

Reason for Changes

Part of the accessibility work.
