maroandClaude Sonnet 5 1cd15aff25 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.

/**
* Minimal in-memory fixed-window rate limiter for a single Node process
* (this app always runs as one process — see server.ts). Good enough to
* blunt abuse of the email-verification resend endpoint without adding an
* external store; resets on deploy/restart, which is an acceptable
* trade-off for this use case.
