A warning never blanks the board or paints the home red: one line, where it belongs #1128

cells.egress=report no longer reaches the board strip or the home. It is now a note on Settings → Capacity. The new tests and the other suites I ran pass, but I did not run the type check. tsc failed here because the bun type definitions weren't found. I also didn't run the full bun test.

• Cause: vitals() pushed an "Egress is reported…" sentence into needs whenever egress was report. The board strip and the home's needs-you section both read needs, so a configuration state showed up as an incident. I removed that push, the EGRESS_REPORTED constant and the egressSetting import from src/kernel/vitals.ts. Vitals now hold only things that need a person: disk, queue wait, stuck runs, an error burst.
• Capacity page: src/web/pages/capacity.ts still says it once, but as a muted note instead of an error-note. I dropped the sentence that said the vitals would also say so.
• Not changed: a real incident still shows as one line on the board strip. The forge's rollout state, which board.ts reads from the guard, was already one line and I left it alone. src/web/studio/home.ts needed no change, since it reads forgeNeedsFor and that now comes out right.
• Tests:

- test/board.test.ts has a new test: with egress on report, the strip reads "All fine", has no need lines and no error-note, and the run card renders. - The existing stuck-rollout test now also asserts exactly one need line with the run card still rendered. - test/web.test.ts checks the home has no error-note and no egress text under report. - test/capacity.test.ts now expects vitals to be empty and the Capacity page to show the note, not an error-note. - In test/vitals.test.ts, the query-count test dropped from 3 to 2 because the egress read is gone. That test was right to change.

• Flaky tests: two capacity tests failed once when I ran four suites together. They pass when run alone, and I think it was load.
• Left out: the forge's own error burst is still a count line without a link. Disk, memory and burst lines have no dedicated page to point at, and I didn't invent one.

To try it, sign in as an admin, set cells.egress to report under Settings → Capacity, then open /board and /. Both stay clean, and the note shows on the Capacity page.

Closes #1109
