[Bug] Display issue on side menu

[xingzhang-suse]

1. Indentation for the “advanced” section - this is not correct = the “advanced” item itself should NOT be indented, only its children should have that indentation (Registries configuration and Vex management). If we don’t fix this, it looks like the “Advanced” section is exclusively tight to the “Images”, not to the “SBOMScanner”

3. Whenever clicking on a link inside the scanner to go deeper than, the navigation on the left fully collapses automatically and hides away the selected “page”.

the desired behaviour = the navigation automatically expands or remains expanded and updates to show where the current page “lives” - please double check the navigation pattern within Rancher, it should be identical.
