feat(ui): migrate activity_metrics tremor Card/Grid/Text/Title to shadcn

Split the tremor import so only AreaChart/BarChart remain; replace the
Grid layout with Tailwind grid classes, Card with shadcn Card (adding
explicit p-6 to preserve tremor's default padding), Text with <p> tags,
and Title with <h3>. Swap raw text-gray-500/bg-gray-50 to semantic
text-muted-foreground/bg-muted. Update the test mock + heading level
query (Title used to render <h2>, now <h3>).
