[SEO] JobPosting structured data, canonical/OG meta, noindex private pages, fuller sitemap

Strategy = Google-for-Jobs + clean indexing. Add schema.org JobPosting JSON-LD to shift & job detail pages (title, description, datePosted, validThrough, employmentType, hiringOrganization, jobLocation, baseSalary) plus Organization + WebSite JSON-LD on the home page (SeoJsonLd helper; System.Text.Json => valid, script-safe). Layout emits per-page canonical, Open Graph + Twitter cards, and applies robots noindex,nofollow to all private/applicant areas (/Admin,/Me,/Employer,/Account,/Preferences) so applicant data is never indexed. robots.txt now disallows those + /resume,/avatar,/report,/push,/notifications and points at the sitemap; sitemap.xml adds facility pages + content pages (Download/Help/Privacy/Rules/Terms).
