fix(frontend): center gate dialogs on the app area, not the browser viewport

Embedded in the Omics Portal the SPA sits to the right of the portal sidebar,
but dialogs used `fixed left-1/2` — centered on the whole browser window, so
gates rendered visibly off-center (overlapping the sidebar).

- AppShell publishes the app area's horizontal geometry (--app-area-left/width)
  as CSS vars on <html> via ResizeObserver + window resize.
- DialogContent centers on those vars (falls back to the viewport when the app
  is standalone, where the two coincide).
- ArtifactGateWidget: narrower — cap at 52rem instead of 70vw.
- tools/replay: resume now returns {id, alreadyActive} JSON — the post-f979ada
  frontend reads result.alreadyActive and a bare 204 broke replay resume.

Verified on the replay harness: with a simulated 300px portal sidebar the gate
centers on the app area (center 790 = 300 + 980/2); standalone unchanged.
