Operator ask: show the graphs next to their fields in the fleet widget, like the
host page's AGENT panel. Each row now renders cpu/mem/disk/load as a value with a
trend sparkline beneath it (1h window), instead of bare numbers.
- _fleet_rows fetches a per-host recent series (cpu/mem/load host-level, disk from
the root mount) in one 1h query and attaches a sparkline per metric to each row.
- widget_table.html lays out a metric cell (label + threshold-coloured value +
sparkline) per field, mirroring panel.html. Threshold colour is computed in the
loop and passed into the cell macro (keeps Jinja macro scope clean).
