Promote a compact Storage summary (breakdown donut + per-category legend
+ reclaimable) onto the System index, replacing the thin Docker strip and
its easily-missed "Open breakdown" link; it links through to the full
breakdown page. Drop the Disk usage trend chart, which duplicated the
Disk gauge's root-mount %.
Extract the donut + segment builders onto SystemStoragePage so the index
summary and the full page share one renderer. This also fixes a donut
stacking bug: the SVG used the final cumulative fraction for every
slice's dashoffset instead of each slice's own running offset, so the
ring only partially filled. It now fills proportionally.
