fix: search race condition + brand detection + contacts + reassess

- loadDomains(): add generation counter so stale auto-advance fetches
  cannot overwrite a newer user-triggered search result; snapshot filter
  state before the first await so URL reflects what was requested; add
  HTTP status check so backend errors surface as toasts rather than
  silent empty results; auto-advance now calls loadDomains() without
  await so the counter increments correctly per page advance

- beauty_ai: word-boundary regex for short brands (≤5 chars) to stop
  'ref' matching 'reference'/'refresh'/'prefer' etc.; merge phones,
  whatsapp and social_links from site_analyzer directly into result
  (more reliable than AI extraction); add contact_whatsapp and
  contact_social fields to AI JSON schema

- db: add requeue_beauty() for re-assessing already-assessed domains

- beauty_main: /api/beauty/reassess/batch endpoint using requeue_beauty

- index.html: Re-assess Selected bulk button, per-row ↺ button in
  Browse and Pipeline, WhatsApp + social links in Pipeline contact panel
