fix: correct links_without_text count and add overall score calculation

1. seo_analyzer.py: Consider aria-label, title, img AND svg as valid
   link text (SVG icon links were falsely counted as "without text")

2. routes_portal_seo.py: Calculate overall_seo score using
   SEOAuditor._calculate_overall_score() before saving to DB
   (was always None because stream route bypasses audit_company())
