feat(ui): layout adaptativo — portrait compacto en teléfonos

- Breakpoint 600dp: debajo, dashboard en una sola columna scrolleable
  (header, perfil+XP+llama compactos, semana, hábitos, mascota, equipo,
  museo); arriba, se mantiene el layout 3 columnas del PRD §5.2
- Onboarding: grid 2×2 en compacto, 4 columnas en tablet
- Orientación desbloqueada en manifest (sensorLandscape fuera)
- WeekRow extraído a componente compartido; TeamAccessCard y
  MuseumMiniCard ahora internal para reuso entre layouts
