Reportes de partido para las 28 ligas con ejes (ligas del modelo intactas)

- Selector de partidos = ligas del modelo ∪ ligas con artefactos de ejes; equipos y
temporadas de ligas nuevas via /api/ejes/teams (endpoint aditivo, nada existente cambia
— verificado contra baseline: /api/leagues?model_only, seasons y teams idénticos).
- Gating por reporte: previo/post NN solo ligas del modelo (con aviso); ejes pre/firma
para las 28.
