refactor(i18n): replace compiled .ts catalogs with direct .po imports

- Remove `lingui compile` / `i18n:compile` script — Vite and Metro LingUI plugins now compile `.po` files on the fly at dev/build time; no manual compile step needed
- Import `.po` files directly in `@sofa/i18n` (`./po/en.po` etc.) and add `po.d.ts` ambient module declaration so TypeScript accepts them
- Add `fallbackLocales: { default: "en" }` and `lineNumbers: false` to `lingui.config.ts`; prefix catalog paths with `<rootDir>` for correctness
- Derive `SupportedLocale` and `SUPPORTED_LOCALES` from `LOCALE_INFO` in `locales.ts` to eliminate the circular import between `index.ts` and `locales.ts`
- Update Crowdin config to use `project_id_env` instead of a hardcoded ID, drop `languages_mapping` (no longer needed), and add `preserve_hierarchy: true`
- Add a daily cron trigger (`0 6 * * *`) to the Crowdin GitHub Actions workflow and drop the now-redundant compile step from it
- Update docs and `AGENTS.md` to reflect that no compile step is required after `i18n:extract`
