fix(ship): i18n ship-repo-section literal strings — unblock main CI

[prellr]

Problem

main CI has been red since #100 (ROA-264 ship-repo-sections) merged. Every CI run since fails at the @multica/views#lint step:

packages/views/ship/components/ship-repo-section.tsx
  69:35  error  disallow literal string: <span ...>{summary.readyToMerge} ready</span>
  74:30  error  disallow literal string: <span ...>{summary.blocked} blocked</span>
  79:28  error  disallow literal string: <span ...>{summary.draft} draft</span>
  90:75  error  disallow literal string: <p ...>No pull requests</p>
✖ 4 problems (4 errors, 0 warnings)

ship-repo-section.tsx shipped with raw JSX text + hard-coded aria-label strings that trip i18next/no-literal-string. Turbo stops the frontend pipeline at lint, so views typecheck/test never even run — the whole frontend CI job is red.

This is not from the upstream-sync PRs (#91/#92/#93). It's a gap in the ROA-264 feature merge; the sync PRs were green where they touched and are unrelated to this file.

Fix

• Reuse the existing project_summary.{ready,blocked,draft}_pill keys (already have {{count}} interpolation in both en and zh-Hans) for the count pills.
• Add a small repo_section block (expand / collapse aria-labels + empty state) to both ship.json locale files so locales/parity.test.ts stays green.
• Wire useT("ship") and the selector-form t(($) => $.…) calls, matching the pattern used across the other ship components.

No behavioral change — same rendered text, now translatable.

Verification (local, on top of current main)

• pnpm -F @multica/views run lint → exit 0 (was: 4 errors)
• pnpm -F @multica/views typecheck → clean
• pnpm -F @multica/views test → 652/652 pass (includes locales/parity.test.ts, mention-suggestion.test.tsx, ship-release-page.test.tsx)
