test(web): share the subagent locale translator

The localized catalog spec introduced two package-local translation stubs: one manually looped over interpolation parameters and the other indexed the Chinese dictionary directly. That duplicates framework test plumbing and can drift from the shared lookup, fallback, and placeholder semantics used by the rest of the client suites.

Use makeTranslate from dsh-client-test-runtime as the single Chinese translator for both catalog and read-only composer assertions. Record the test-only workspace dependency in the ui-subagent manifest and lockfile; no production dependency or runtime bundle edge is added.

This removes twelve lines of local translation behavior while preserving the same Chinese assertions and exercising the shared interpolation path. Both ui-subagent test files pass with all 28 tests, the package TypeScript project checks cleanly, and the staged diff passes formatting, lint, and whitespace hooks.
