fix(ui): status-code donut as 5th KPI block — crisp path arcs, no clipping, compact chips

- move status distribution out of the full-width standalone card into the top KPI row as a 5th small block (aligned with the four KPI boxes)
- swap stroke-dasharray circles for SVG path arcs inside a rotated <g>: keeps each slice crisp and prevents the thick stroke clipping against the viewBox edge
- compact 108px donut + wrap-able status chip legend (hover title shows code/reqs/percent)
- drop redundant dashStatus subtitle; simplify title
- deployed to /usr/local/bin/llmsproxy (bak .bak.20260811j), server active
