feat(lea): bulles 'Léa exécute' stylisées + templates par event

J3.4 — distinction visuelle entre :
- Bulles chat normales (fond bleu clair, prefixe 💬, taille standard)
- Bulles d'action Léa (fond gris clair, encadré subtil, icône sémantique
  en couleur, libellé court, métadonnées discrètes en pied)
- Bulle paused supervisée (jaune, boutons interactifs — déjà en J3.5)

Templates de libellés volontairement neutres : le contexte métier (UHCD,
peakflow, J12.1, IPP 25003284…) provient des payloads émis par le pipeline
côté serveur, pas de hardcoding dans le client.

Mappage events → bulles :
  lea:action_started   ▶ bleu  "Démarrage : {workflow}"
  lea:action_progress  ⋯ bleu  "{step}" ou "Étape {current}/{total}"
  lea:done             ✓ vert / ✗ rouge selon success
  lea:need_confirm     ?  bleu  "{action.description}"
  lea:step_result      ✓ / ✗ / · selon status
  lea:resumed          → vert  "Reprise"
  lea:resume_acked     (silencieux côté UI)
  lea:abort_acked      (silencieux côté UI)
  événement inconnu    · gris  fallback neutre

18 nouveaux tests pytest (templates + extract_meta).
Total branche : 47/47 verts.

+  2. Template multi-scale            ~80-150ms  (robuste aux changements de taille)
+  3. OCR (docTR)                     ~500-1000ms (texte uniquement)
+  4. Static fallback                 ~0ms       (coordonnées d'origine)
+
+Note : les feature matchers (ORB/AKAZE) ne sont pas adaptés aux petites
+ancres UI (< 200x200px) — trop peu de keypoints distinctifs.
