Introduces per-area identity hues as reusable tokens (--page-updates/backups/
ssh/system + -rgb companions) and a generic .admin-action-btn that takes its
colour from --page set on the card. The Overview buttons now read in their
area's hue — Updates blue, Backups emerald, SSH violet, System amber — with the
icon following via currentColor; "Update now" is the filled (primary) variant.
The tokens are the foundation to extend each area's identity (page headers,
accents) going forward, not just these buttons.
