Writing down what each endpoint actually guarantees made the places it
didn't obvious — shell arguments reaching a crontab or a bash -c
unescaped, master.conf written without tmp+rename, and conf edits that
could be saved without ever being parsed.
Custom Scripts (the Scheduler page's inline editor) used to save into the
git-tracked Custom/ folder, so anything saved there would end up on GitHub.
They now live in /boot/config/plugins/user.scripts/Varaverk/Scripts, same
folder family as Unraid's own User Scripts plugin. Import Script lets you
browse the whole server and move an existing script in instead of only
creating new ones inline — always a move, never a copy, so no stray
duplicate is left where it came from.
