feat(dashboard): adopt Tremor for charts — first integration
Brings Tremor (Apache-2.0) in as the project's chart component
library and converts the response-time chart as the first
integration. Tremor is distributed copy-paste ("Tremor Raw") so
the components live under `src/components/tremor/`; the only
runtime peer dependency added is `recharts`. Two small local
adaptations to the vendored `BarChart`:

- `cx` (Tremor's `clsx`+`twMerge` helper) → our `cn` from
  `@/lib/utils`, aliased locally to keep diff vs upstream minimal.
- `@remixicon/react` legend-slider icons →
  `lucide-react`'s `ChevronLeft` / `ChevronRight`, since
  `lucide-react` is already a project dep.
- `ChartTooltipProps.label` widened from `string` to
  `string | number | undefined` to match recharts 3.x (Tremor's
  source still types it for recharts 2.x).

Why Tremor and not a wider switch (Mantine, HeroUI):
- The dashboard ships ~700 lines of hand-rolled SVG across three
  chart files — a focused charting library is the highest-ROI
  addition without touching the wider component surface.
- Tremor is Tailwind-native and built on the same Radix/Base UI
  layer as the existing `src/components/ui/*`, so it composes
  rather than displaces.
- Apache-2.0 + copy-paste distribution means no upgrade lock-in.

What this PR does
- Adds `src/components/tremor/{bar-chart.tsx,chart-colors.ts,
  get-y-axis-domain.ts,use-on-window-resize.ts}` (vendored from
  tremorlabs/tremor with the adaptations above).
- Installs `recharts@^3.8.1` (React 19 + Next.js 16 compatible).
- Rewrites `src/components/dashboard/response-time-chart.tsx`:
  drops 130 lines of bespoke SVG math (axis scaling, bar
  positioning, grid lines, tooltip rendering), reuses the same
  card/header/empty-state shell.

Deferred (own follow-up PRs)
- `pipeline-donut.tsx` — has user-customisable per-stage hex
  colours; Tremor's palette would override them. Needs either a
  small upstream patch or a `colors` override path.
- `conversations-chart.tsx` — area-chart conversion (largest of
  the three, 341 lines).
- The previous hand-rolled bar chart drew a horizontal dashed
  "target N minutes" reference line. Tremor BarChart doesn't
  expose Recharts primitives, so for now the target is promoted
  to a header pill (`target 5m`). On-chart reference line is a
  follow-up — either via a positioned overlay or an upstream
  `referenceLines` prop.

Verification
- `npm run lint`   → 0 errors (same 20 pre-existing warnings).
- `npm run typecheck` → clean.
- `npm test`       → 319/319 pass.
- `npm run build`  → succeeds, dashboard remains a static route.
