test(mgc): cover fn_status_split output 17 (% of capacity); fix stale 17→18 count

Browse Source 
The dashboard fan-out grew to 18 outputs (output 17 = '% of capacity' chart)
but dashboard-fanout.integration.test.js still asserted 17 and had no PORT
entry or coverage for output 17. Add chart_pctcap (17) with populated (State C,
flow/capMax×100) and degraded (State A → null-drop) assertions, fix the count
assertion, and add the fan-out enumeration table to _output-manifest.md per
.claude/rules/output-coverage.md.

## Example flow fan-out — `examples/02-Dashboard.json :: fn_status_split` (outputs: 18)
Delta-caches Port 0 then fans one msg per dashboard widget. Charts return the
whole msg as `null` (drop the output) when their source is missing — never
`{ payload: null }`. All ports covered by `test/integration/dashboard-fanout.integration.test.js`.
