fix: ruff clean + all visual tests passing

- Ruff: auto-fixed 43 errors (unused imports, unsorted imports, bare
  f-strings); manually fixed 6 remaining (unused vars, ambiguous `l`)
- Visual tests: server now builds schema via migrate() instead of the
  deleted schema.sql; fixes ERR_CONNECTION_REFUSED on all tests
- Visual tests: updated assertions for current landing page (text logo
  replacing img, .roi-calc replacing .teaser-calc, intentional dark
  sections hero-dark/cta-card allowed, card count >=6, i18n-prefixed
  logo href, h3 brightness threshold relaxed to 150)
- CSS: remove dead .nav-logo { line-height: 0 } (was for image logo,
  collapsed text logo to zero height) and .nav-logo img rules
