Scale up radix-mira component sizes for a portfolio context

The new shadcn 'radix-mira' style targets dense dashboards. For a personal
academic site the ultra-compact defaults (10px badge, 12px button/card,
14px card title) read as broken. Updated to readable sizes:

- card.tsx: text-xs/relaxed → text-sm base; CardTitle text-sm font-medium
  → text-base font-semibold leading-tight; CardDescription text-xs → text-sm
- badge.tsx: text-[0.625rem] h-5 px-2 → text-xs h-6 px-2.5
- button.tsx: text-xs h-7 px-2 → text-sm h-9 px-4 (default size)
- tabs.tsx: TabsTrigger text-xs px-1.5 → text-sm px-3; TabsContent
  text-xs/relaxed removed; TabsList h-8 → h-10
