fix(mealie): fallback heredoc if start.sh missing before backup

Instead of recreating start.sh from a heredoc after CLEAN_INSTALL wipes
/opt/mealie/*, simply back it up before the wipe and restore it together
with mealie.env. Simpler and avoids any drift between the hardcoded
heredoc and what was actually installed.
