Four spots told the operator to read the SPA footer to confirm a
deploy landed. The footer no longer renders a version, so restating
that would send an operator looking at a control that no longer
exists. Point them at /api/status instead; the version field itself is
unchanged.
The previous commit inserted 500+ lines into notify.rs, moving
register_push and register_telegram_webhook. Reanchor the two
deployment.md line refs; the other seven refs in that file are before
the insertion point and are unchanged.
Document the new retire-on-change contract in reference.md.
