Set up logic for the final backup - #2882

📝 WalkthroughWalkthroughThe backup pipeline now propagates ChangesBackup expiration and sunset finalization
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟠 High · up to The change adds a one-time final-backup workflow, but the current implementation can mark incomplete clone retries as finished, create duplicate backups on repeated read-only transitions, and apply incorrect expiration behavior, potentially leaving apps without a required final backup or retaining backups for the wrong period.

- Around line 589-590: Thread the correctly named :expires-at value through both
backup pipelines: update the producer currently writing :expire-at, preserve it
in snapshot flush items, add it to process-with-clone-pool inputs, and forward
it from start-upload-process to every complete-streams call. Ensure
complete-streams receives the actual expiration value rather than defaulting to
seven days.
- Around line 1102-1108: Update the final-backup flow around process-with-clone
and process-with-snapshot so it waits for the selected process via
:wait-for-finish and checks that it completed without failed apps before calling
sunset/update-flag! for final-backup-status. Keep the status pending when
uploads are unfinished or failures are recorded, including clone retry failures.
In `@server/src/instant/sunset.clj`:
- Around line 106-108: Update set-stage! so final-backup-status is initialized
to "pending" only when transitioning into :read-only, while repeated :read-only
calls preserve an existing "completed" status and do not reschedule the final
backup.

Takes one final backup for each app when we go to read-only mode.
When we update the sunset stage to read-only, we'll also set a flag that tells us to take one final backup. That backup is set to expire 1 year + 1 month after it's taken. When the backup succeeds, we'll update the backup status so that we no longer take any backups.
Also includes a flag to take backups via a snapshot instead of creating a clone.
