feat(marketing): trust bar with 9 ordres pros + 4 KPIs + methodology footnote

- Section AFTER hero, white bg with brand-border y-borders
- 9 monogram placeholders (gradient circles with initials, NOT official
  logos to avoid licensing issues + false-endorsement exposure)
  hover from opacity-50 to opacity-100 for subtle interaction
- Eyebrow phrasing 'MAPPÉ AUX 9 ORDRES PROFESSIONNELS' (factual scope,
  not 'CERTIFIÉ PAR' which would be a false-endorsement claim under
  LPC art. 219 / Competition Act s. 52)
- 4 KPIs with grad-text numbers: ~5 min/heure, 95%+ FR-CA, 0$ par user,
  100% local — each with a 1-line context line and a small subtext
- Methodology footnote: 'Précision mesurée sur 50 heures d'audio
  interne, détails sur demande' — defensible disclosure for the 95%
  claim (LPC art. 219 hygiene)
- 4 new tests verify ordres list, factual phrasing, KPIs, footnote
