chore(release): v1.28.36 — re-importing after a failed Apple Health import actually retries

The v1.28.33 rollup + staging fixes were correct but never reached the
reporter's case: the upload dedup keys on the content SHA-256 and the
lookup matched a previously FAILED job too, so re-uploading the same
export.zip returned the dead job's id and replayed its stale
failureReason without ever staging or sending again. The dedup now
excludes failed rows (short-circuits only on queued/unpacking/parsing/
upserting/done); the same bytes retry cleanly. A redundant staged upload
is unlinked on a dedup hit instead of leaking in the staging dir.

reconcileOrphanImportJobs no longer unconditionally fails every
non-terminal ImportJob at boot: it now checks pg-boss job state plus a
progress heartbeat (new import_jobs.updated_at, migration 0242), so a
split or multi-worker deployment cannot kill an import running in
another worker. The missing-staging message names the separate-container
cause explicitly, with a matching note in docs/self-hosting/scaling.md.
