refactor: Suppression de 13 écrans redondants

Nettoyage des doublons pour éviter la redondance :

Suppressions (liste.xhtml redondants avec écrans racine):
- devis/liste.xhtml
- employes/liste.xhtml
- equipes/liste.xhtml
- factures/liste.xhtml
- maintenance/liste.xhtml
- materiels/liste.xhtml
- messages/liste.xhtml
- notifications/liste.xhtml
- planning/liste.xhtml
- rapports/liste.xhtml
- stock/liste.xhtml

Suppressions (inconsistance nouveau/nouvelle):
- equipes/nouvelle.xhtml
- factures/nouvelle.xhtml

Stratégie:
- Un seul écran liste par module (racine)
- Standardisation sur nouveau.xhtml

Résultat: 163 écrans restants (vs 176 avant)
