The flow panel's last merge gates speak the home page's language #9954

The newest ten merge-queue gates on /boards and /flow read as plain rows, not a card.

Done when:

• [x] gatesCard (src/web/pages/boards-gates.ts) renders a section with an h2 and rows in a .list, no class="card.
• [x] On red, the row still names the first failing test and its first error; only repositories the reader may see are listed.
• [x] test/boards-gates-language.test.ts holds the above on /boards.
• [x] The new test fails on main today and passes with the change; bun test is green.

Files: src/web/pages/boards-gates.ts, test/boards-gates-language.test.ts (new)

Keep: flow-panel.ts untouched beyond the call; the read stays one query.

Pattern: test/accounts-language.test.ts (#9948) and the pages moved off card() before it. A new component class goes in docs/design/areas/<area>.md; bun scripts/design-lint.ts passes.
