Add email verification, personal calendar feed, and full SEO implementation

- Customer accounts now require email verification (hashed, single-use, time-limited tokens) before they can request/confirm bookings, with resend flows on login/account/booking widget and rate limiting. - Admins get a private, rotatable iCalendar (ICS) subscription feed of their confirmed bookings and public events, timezone-correct for Europe/Berlin including DST, never exposing meeting passwords. - Adds a full SEO layer: per-page canonical/OG/Twitter metadata with CMS-editable overrides and content-derived fallbacks, a dynamic sitemap.xml and robots.txt driven by real published content, JSON-LD (Organization/LocalBusiness, WebSite, WebPage, BreadcrumbList, Service, Event, BlogPosting) that never fabricates data, and a CMS-managed redirect table for changed slugs. - Global ANOUMA-naming audit: the brand name is never used to label personal account/calendar areas anywhere in the app, CMS, or emails.
