Fix metadata modal not scrolling on desktop

[Copilot]

Long metadata content was clipped on desktop — the modal panel overflowed the viewport with no way to scroll to the rest of the content.

Root cause

Modal uses sm:overflow-y-hidden on its outer wrapper to prevent page scroll on desktop, relying on the scrollable prop to opt the body div into sm:overflow-y-auto + sm:flex-1 within a max-h-[90vh] flex column. MetadataModal never passed scrollable, so content beyond the viewport was silently clipped by the panel's overflow-hidden.

Change

• MetadataModal.tsx — add scrollable to the <Modal> render:

- <Modal loading={loading} title="" onRequestClose={onRequestClose}>
+ <Modal loading={loading} title="" scrollable onRequestClose={onRequestClose}>
