Fix tooltip styling by using explicit CSS variable references

Tailwind v4 utilities weren't picking up the color variables properly.
Changed from:
- bg-popover → bg-[var(--color-popover)]
- text-popover-foreground → text-[var(--color-popover-foreground)]
- border-border → border with style={{ borderColor: 'var(--color-border)' }}
- fill-popover → fill-[var(--color-popover)]

This ensures the tooltips get proper background, text color, border, and
arrow fill using our theme colors.
