fix(downloads): clamp editor hover-scrub popover inside the track

Browse source 
The hover-scrub thumbnail was centered on the cursor with a fixed -translate-x-1/2, so near the
filmstrip's right (or left) edge it overflowed the modal and triggered a horizontal scrollbar. Now
its left edge is clamped to [0, trackW - popoverW] so it shifts inward at the edges and stays fully
within the viewport. Verified at both edges in a real browser.
