fix(dashboard): render verificado en dispositivo EMUI

- Header reestructurado: en el Huawei de prueba el Row con Alignment.Bottom
  + SpaceBetween medía ~270dp fantasma, aplastando la lista de hábitos a
  altura 0 (las tarjetas ni se componían). Ahora es columna simple con
  chips en fila propia y maxLines acotados.
- LazyColumn con weight(1f) en vez de fillMaxSize dentro de Column sin peso.
- Singular '1 día de racha' / '1 día' (antes '1 días').
