geenforce: move settings into the Settings rail

The client IP allowlist config was a tab inside the GE-Enforce section; move
it to the Settings rail via get_settings_cards (matches printedparts / zabbix /
dell). Route relocated from /geenforce/settings to /settings/geenforce; the
in-section Settings tab is removed. Card: Settings > GE-Enforce.
