Add a consolidated Recovery page that answers "what do I do if Sencho
breaks?" in one place. It covers getting back to a working state when
Sencho itself fails, a stack deploy fails, an admin is locked out of
sign-in, Docker is unavailable, or a remote node is unreachable, and
summarizes each path with a link to the authoritative detail page rather
than duplicating it.
The page opens by stating the core safety fact: Sencho keeps its state in
DATA_DIR and COMPOSE_DIR and treats compose files on disk as the source of
truth, so recovery is mostly file-level and running containers are
unaffected by a Sencho outage. It points to Backup & Restore as the
prerequisite.
Link the guide from the README documentation section, the quickstart
"where to next" cards, and the top of the troubleshooting page.
