fix(ct): keep Craftopia saves inside serverfiles (#5131)

Craftopia joins its install folder and the relative savePath from ServerSetting.ini with no separator, so saves went to serverfilesDedicatedServerSave beside serverfiles. A new pre-start fix (fix_ct.sh) moves an existing stray save folder into serverfiles and sets savePath to the absolute path. If saves exist in both places it warns and changes nothing, and an absolute savePath set by the owner is left alone.

Fixes #5130
