feat: 5 fixes — dead site scoring, Kit Digital precision, social icons, GMB detection, social/GMB weighting

1. scorer: dead sites capped at 5 (was scoring HOT from SSL/CMS signals)
2. Kit Digital: require explicit kit-digital/agente-digitalizador signals;
   generic EU logo patterns (fondos-europeos, logo-ue, cofinanciado) removed.
   Gemini kit_digital_confirmed now overwrites heuristic in DB.
3. Browse table: social links replaced with compact coloured icon badges
   (fb/ig/in/x/tt/yt) linked to the profile URLs
4. site_analyzer: added has_gmb / gmb_url detection (Maps embed, Place links,
   LocalBusiness schema); fed to Gemini prompt
5. scorer: +5 no-social, +3 reachable contact; Gemini prompt includes GMB and
   social media management as sellable services; modal shows GMB/social status
