sometimes scroll bar style not working

Description

Fixes the modal scrollbar styling that intermittently failed to apply. The scrollbar-color declaration was missing a track color and scrollbar-width, so browsers would fall back to the default scrollbar appearance in some cases.

How has this been tested?

Note

Low Risk
CSS-only presentation tweak in the modal package with no auth, data, or API impact.

Overview
Fixes intermittent default scrollbars in the Web3Auth modal by tightening Firefox-oriented scrollbar styling on .w3a-parent-container > *.

Those descendants now use scrollbar-width: thin and scrollbar-color: #e5e7eb transparent (thumb plus transparent track) instead of a thumb-only color. The duplicate scrollbar-color on .w3a--social-container is removed so styling is centralized on the parent rule.

Nested scrollbars lose styling

Medium Severity

The commit drops scrollbar-color (and does not add scrollbar-width) on .w3a--social-container, while scroll styling now lives only on .w3a-parent-container > *. The social login and wallet lists that use overflow-y-auto are nested descendants, not direct children, and scrollbar-color is not inherited, so those scrollbars can still fall back to the browser default.
