fix(stems): surface archive job timeouts on mobile

[dylanjeffers]

Closes #14536.

Problem

DownloadTrackArchiveDrawer keyed hasError off jobState.state === 'failed' alone:

const hasError =
  !isStartingDownload &&
  (downloadError || initiateDownloadFailed || jobState?.state === 'failed')

A stems archive job that never leaves waiting is reported as a valid non-terminal state forever, so the drawer spun indefinitely — no error, no retry affordance, no way for the user to tell it would never finish.

#14535 added STEMS_ARCHIVE_POLL_TIMEOUT_MS to useGetStemsArchiveJobStatus and wired the resulting isTimedOut into the web modal, but the mobile drawer was never updated. It destructured only data, dropping both isTimedOut and isError.

Why this isn't hypothetical

During the 2026-07-28 archiver outage the worker lost its Redis locks when archiver-redis was recreated, kept all five concurrency slots, and 24 jobs sat in waiting across 15 tracks for ~7 hours (AudiusProject/pedalboard#77). Web users got an error and a retry link after 15 minutes. Mobile users got a spinner that could never resolve.

Change

Destructure isError and isTimedOut from the shared hook and fold them into hasError, matching the web modal exactly:

const hasError =
  !isStartingDownload &&
  (downloadError ||
    initiateDownloadFailed ||
    jobState?.state === 'failed' ||
    (!!jobId && (isJobStatusError || isJobTimedOut)))

The !!jobId guard mirrors web — job-status errors only count once a job actually exists, so a pending create isn't reported as a failed download.

No hook changes; the timeout and flag already existed and were simply unused here.

Scope

Deliberately narrow. The error copy shown on both platforms is still the hardcoded "check your connection" string even when the archiver returns a real failedReason — that's #14537 and unchanged here.

Testing

• tsc --noEmit clean; confirmed via --listFiles that the drawer is actually in the checked program.
• eslint --ext=ts,tsx src/components/download-track-archive-drawer/ clean.
• Not exercised on a device — reproducing it requires an archiver whose worker is wedged, which is the condition pedalboard#84 exists to make recoverable.
