- Sidebar now groups items: Overview at top, a 'Config' heading over the config
categories, and the existing 'Tools' heading over SSH Access.
- Breadcrumb reflects the group: config pages read 'Config' (was 'Admin'), SSH
reads 'Tools', Overview stays 'Admin'.
- SSH Access page restyled to the config page's section layout
(.config-category/.domains-wrapper sections) instead of backup-style cards, so
it matches the other Admin config pages.
