feat: layout responsivo y KPIs adicionales en dashboard

Grid de charts pasa de 2 a 4 columnas con altura dinamica (35% del
espacio disponible). Se eliminan los paneles Activity y Extras,
moviendo Unit Tests y Proposals a la fila de KPIs (ahora 8 cards).
Se reduce spacing entre secciones para aprovechar mejor la pantalla.
