feat(gui): GUI V6 G4 — alignement visuel sur la maquette v6 (option A)

Refonte de la couche présentation pour reprendre docs/ui_mockup_v6.html, sans
changer de techno UI ni la logique G1-G3.

- theme.py : 4 thèmes aux tokens EXACTS de la maquette (sombre #1a1a2e/#16213e/
  #e94560, clair, médical, neutre), palette complète + status_color.
- ui_kit.py (nouveau) : composants stylés (Card titrée, boutons primary/secondary/
  success/pilule, StatCard, ToggleRow) appliquant la palette.
- app.py : shell étroit, header identité + version + statut licence + liseré accent,
  barre d'onglets custom (plus de CTkTabview brut), navigation par recréation,
  changement de thème à chaud.
- tab_usage : carte Apparence (sélecteur de thème), dropzone stylée, grille formats,
  barre d'actions, progression à étapes + journal, résultats en cartes statistiques.
- tab_config : sous-navigation Réglages/Masquage/Partage/Règles ; Réglages câblé au
  ConfigState (profil, moteurs NER, dossier sortie).
- tab_about : grille d'informations + bloc licence (logique inchangée).

Logique inchangée : engine_bridge, config_state, license_client/store, runner.
Tests : +9 (theme). self-test exit 0, 55 tests gui_v6, 202 tests/unit (0 régression).
Smoke construction headless (Xvfb) : 3 onglets × 4 thèmes rendus sans erreur.
Pas de pywebview, aucun .exe.
