j/k, enter, esc and ? on resilience, with test/keys-<page>.test.ts #10802

/resilience now answers j/k, Enter, Esc and ? from the shared shell. I added no JavaScript. The new test, resilience-page, help-keys and resilience-fit pass; tsc, design-lint and gate.ts are clean. resilience-fit skipped its phone-look check because there is no chromium here.

What changed

• Each nightly-job line in src/web/pages/resilience.ts is now a data-nav row. j/k move focus between them, Enter follows the row's "Output" link to /resilience/nightly/:job, and Esc on that page returns to /resilience.
• test/keys-resilience.test.ts drives the real rendered page for an admin, using the shared expectListKeys helper:

- j/k focus the nightly rows. - Enter opens the output page. - Esc on the output page goes back. - No key fires while a text field has focus.

• The test also checks that exactly one data-nav row is drawn per nightly job and none inside the Protections list.

Left out

• The Protections rows have no data-nav. Each is a sentence plus a test path with no link or form, so Enter would have nothing to open.
• The backups line and the Maintenance link are single links, not a list, so I left them as they were.
• The nightly rows have no extra focus styling beyond the browser's default focus ring.

Try it: sign in as an admin, open /resilience, press j then Enter on a nightly job, then Esc.

The push was refused until a commit carried a Try: line, so the branch ends with an empty commit that holds one.

/resilience now answers j/k, Enter, Esc and ? from the shared shell, with no new JavaScript. The check failed because the one-line header comment in test/keys-resilience.test.ts ran past 160 columns. I wrapped it across several lines. test/header-width.test.ts and test/keys-resilience.test.ts pass here, and the fix is pushed. I haven't seen the forge's check re-run on it yet.

The push hook refuses a push without a Try: line in a commit message, so the empty "Try:" commit and this fix's message each carry one.
