fix: beauty frontend server-side filtering and bulk actions

- add keyword and tld params to get_enriched() in db.py (LIKE on domain + page_title)
- forward keyword/tld through /api/enriched in beauty_main.py
- rewrite beauty/index.html loadDomains() to pass all filters server-side via URLSearchParams
- track domainsTotal from API response for correct pagination display
- add Pre-screen Selected and B2B Assess Selected bulk action buttons
- add per-row Screen and Assess buttons
- goSearch() resets to page 1 before fetching
