fix: add -settingStatus CLI flag to reduce DB inits during install/update

Worker nodes with remote MariaDB experienced slow configuration because
config_after_update() and config_after_install() made 5-8 separate
x-ui setting CLI calls, each spawning a new Go process and re-initing
the DB connection. Add a single -settingStatus flag that returns all
needed info in one call, reducing DB inits from 5-6 down to 2.
