fix(seo): render translated content for language pages

[ThisIs-Developer]

The 14 non-English URLs reported as "Crawled - currently not indexed" returned the same English body and first-run welcome document despite localized metadata. This change serves useful translated welcome content in the initial HTML and gives new visitors a translated starter, so each language URL has matching content before and after JavaScript initialization.

Changes

• Render welcome content for all 15 supported languages and preserve saved documents during language changes.
• Keep public URL language, titles, canonicals, schema, and response headers consistent, including the English root and Brazilian Portuguese.
• Exercise the Pages middleware in the development server and add npm run audit:seo for deployment checks.
• Preserve intentional redirects for /?lang=en, /tips, and /index.html; keep them out of the sitemap.
• Update localization documentation, synchronize desktop resources, and include a URL-by-URL Search Console report with deployment and validation steps.

Validation

• npm run build passed.
• 7 Chromium SEO tests passed, including all 15 initial responses, rendering without JavaScript, static-host fallback, redirects, and document preservation.
• 4 Chromium startup/release-note smoke tests passed.
• The GitHub importer localization regression passed across all 15 interface languages.
• The local audit:seo check passed for all 15 canonical URLs and the expected redirects.
• Visually checked French desktop rendering without JavaScript and French mobile rendering; no mobile page overflow or browser errors.

After deployment through Cloudflare Pages with Functions enabled, run npm run audit:seo, inspect the changed URLs in Search Console, and request reassessment. These checks establish technical eligibility; Google controls indexing, and intentional redirects may remain excluded. Translated product copy still benefits from native-speaker review.
