The system page showed the disk of the host volume, not the budget the
instance can actually fill — on a Hostsharing Managed Webspace that is a
group quota, tighter than the volume by an order of magnitude, so the
warn/critical highlighting could never fire before a build failed with
"Disk quota exceeded".
DiskQuota parses `quota -u -g --no-wrap --raw-grace` and picks the
tightest of the user quota, the group quota, and the volume itself;
SystemMetricsCollector reports whichever binds, resets the disk
min/max/avg when the binding source changes, and the system page names
the source in its info line. A host without a binding quota (Docker
hosts, developer machines) renders exactly as before.

Die alte GitHub-PR#14 kollidiert mit der Gitea-Nummerierung, die nach dem
Umzug bei 1 neu beginnt; PR#16 ist die tatsächliche Nummer auf git.javagil.de.
