Two fixes in loadCurrentShare() / constructor:
1. Reset dirty flag after initial load so opening the Properties dialog
(or triggering applyChanges from another plugin in the same dialog,
e.g. a sibling FTP share tab) doesn't rewrite the share with stale
combo values.
2. Strip Samba domain/authority prefixes like "DOMAIN\user" or
"Unix User\user" when parsing usershare_acl, so the username
comparison against /etc/passwd users succeeds and the combo boxes
reflect the actual saved permissions.
Applied identically to kf5 and kf6 variants.
