Subject: [PATCH] fix(tracker-web): telemetry ingest auth (X-Install-Token) +
 show cost as approx

- telemetry proxy attaches an X-Install-Token (derived from the payload, with a
  fallback) so the backend ingest auth gate stops returning 401 on browser beacons.
- job-detail Cost shows ~$x.xx approx when the figure is estimated (token-based).
