test(i18n): check display-only error messages in one source scan

What & why

The translation audit read every source file twice, once for direct uses and once for aliases. Run both checks on the same contents. This preserves the file filters, patterns and line diagnostics while avoiding the second traversal that contributed to a macOS timeout.

How I tested it

  • On this branch, macOS arm64 with Bun 1.4.3 and TERM=dumb: from packages/i18n, bun test test/display-only.test.ts — 10 pass, 0 fail.
  • This patch was also part of the combined macOS verification for #9625: all 30 repository test tasks passed in one uncached run, with default workers and timeouts. Repo-wide lint and typecheck passed on that combined checkout.

Summary by cubic

Combines the direct-use and alias checks in the i18n display-only test into a single file scan, removing the second traversal that contributed to a macOS timeout while preserving file filters and line diagnostics.
