Pull request overview

This PR introduces internationalization (i18n) support to the cert-manager Headlamp plugin by wiring UI labels/messages through useTranslation() and adding locale resources/config so the plugin can ship translations.

Changes:

• Replaced hard-coded UI strings across cert-manager list/detail views with t('...') lookups.
• Updated shared components/helpers to support translated labels/messages (including passing t into processIssuerExtraInfo).
• Added locale configuration in package.json and created locales/<locale>/translation.json files (with en populated).

cert-manager/src/components/orders/Detail.tsx:74

• The Wildcard value is rendered via boolean.toString(), which stays as "true"/"false" (not localized). Since this view is now i18n-aware, render it as translated Yes/No for consistent localization.
  cert-manager/src/components/challenges/Detail.tsx:73
• This fallback hard-codes the English string "false" and uses boolean.toString() for the true case, which is not localized. Prefer using translated Yes/No (and keep the existing default-to-false behavior when wildcard is undefined).

                value: item.spec?.wildcard?.toString() || 'false',

cert-manager/src/components/challenges/Detail.tsx:87

• Presented/Processing are displayed via boolean.toString(), which produces "true"/"false" and won't be localized. Prefer translating these boolean values (e.g., Yes/No) to match the rest of the UI.

                        { name: t('Presented'), value: item.status.presented.toString() },
                        { name: t('Processing'), value: item.status.processing.toString() },

cert-manager/src/components/common/processIssuerExtraInfo.tsx:26

• This optional boolean is displayed via toString(), yielding "true"/"false" (not localized) when set. Since this is user-facing, consider mapping booleans to translated Yes/No while keeping empty when undefined.

            { name: t('Skip TLS Verify'), value: spec.acme.skipTLSVerify?.toString() },
