[Bug] Storyline stats: DeadlineCountdown style mismatch in stat boxes

[realproject7]

Problem

PR #805 placed DeadlineCountdown inside a stat box styled as text-sm font-bold text-foreground. But DeadlineCountdown renders its own inner <div class="text-xs"> with text-accent font-medium, which overrides the parent box styling. The deadline stat box looks visually inconsistent with Market Cap and Supply Minted boxes.

Current rendering

• Market Cap: text-sm font-bold text-foreground ✅
• Supply Minted: text-sm font-bold text-foreground ✅
• Deadline: text-xs font-medium text-accent ❌ (overridden by DeadlineCountdown internals)

Solution

Either:

• Update DeadlineCountdown to accept optional className props that override its internal styling
• Or create a thin wrapper in the stat box that strips DeadlineCountdown's wrapper div

The value text should render as text-sm font-bold text-foreground to match the other two boxes. The "expired" state can keep text-error color.

Acceptance Criteria

• Deadline stat box value matches Market Cap and Supply Minted styling
• Countdown text renders as text-sm font-bold
• "expired" state still shows in error color
• No changes to DeadlineCountdown in other contexts (storyline cards, etc.)
