Wires the chart surface end-to-end:
- frontend/src/projects-chart.tsx — standalone page shell with title
row, inert control chips (Slice 3 wires them live), undated hint slot,
and the mount target for the SVG renderer.
- frontend/src/client/projects-chart.ts — boot client that parses the
project id from the URL, loads project metadata for the header,
mounts the renderer, and reveals the undated hint when the layout
reports clipped/undated rows.
- frontend/build.ts — registers the new bundle + HTML output.
- frontend/src/client/i18n.ts — 11 new DE+EN keys under projects.chart.*
+ projects.detail.smarttimeline.open_chart (the Verlauf link).
- frontend/src/projects-detail.tsx — "Als Chart anzeigen ↗" link in
the SmartTimeline controls, opens /chart in a new tab.
- frontend/src/client/projects-detail.ts — resolves the chart href in
renderHeader once project.id is known.
`bun run build` clean, `go build ./...` clean, 27/27 chart tests pass.
Design ref: docs/design-project-chart-2026-05-09.md §8.1 + §8.2 + §12.
