Calm 2.0 Fase 2: check-in guiado full-screen (build 52)

El ritual mensual como flujo paso a paso en vez de formulario:
- Una fuente por pantalla: valor anterior a la vista, entrada grande (40pt
  rounded), delta en vivo (chip verde/rojo con importe y %), sugerencia de
  portapapeles, 'Igual que el mes pasado' y 'Omitir'
- Barra de progreso del ritual; cancelable solo al inicio (interactiveDismiss
  bloqueado a mitad para no perder valores)
- Reflexión: mood (5 estados existentes) + nota de una línea
- Cierre: total nuevo, delta del mes, streak, compartir y haptic de éxito
- Persistencia por los MISMOS caminos que Quick Update (Snapshots) y el journal
  (MonthlyCheckInStore → JournalEntry): coherente con el resto de entradas
- Entrada: CTA del check-in card en Home (fullScreenCover); la fila de
  completado sigue navegando al journal
- Fix: referenceDate congelada en @State al presentar — el card la recalcula al
  guardar y SwiftUI re-evaluaba el contenido del cover cambiando el mes a mitad
  de flujo
- --pending-checkin en ScreenshotMode (revierte el seed a 'mes pendiente') +
  UITest testGuidedCheckInFlow end-to-end (valor → skips → mood → cierre) ✓
- Strings ×7 idiomas
