refactor(i18n): derive eloqnt locales from i18n config, drop ui-components from srcPath

The locale list now comes from packages/i18n/src/config.json (enabled
locales only) instead of being duplicated. 'infer' is not used because it
would pick up the disabled ar.json from disk.

packages/ui-components does not use next-intl — components receive
translated strings as props — and removing it from srcPath leaves the
lint result unchanged (verified: 0 errors, 562 warnings).
