Revert "hogar compartido: colaboracion entre cuentas sobre Firestore"

El hogar compartido cambia donde viven los datos, asi que se va a la 3.0 y la
2.x queda para correcciones. El trabajo sigue vivo en la rama 3.0.0 (163fd60).

Importante para esta rama: esto tambien retira el entitlement
com.apple.developer.applesignin, que sin la capability marcada en el App ID
habria roto la firma al subir la 2.1.1 a TestFlight.

This reverts commit 163fd60.

-/// How changes are detected without touching every mutation site in the app:
-/// each synced document carries a fingerprint of its content, and the last
-/// fingerprint pushed or received per document (the "shadow") is persisted.
-/// Local content whose fingerprint no longer matches the shadow is a local
-/// edit; an id present in the shadow but gone locally is a local delete, which
-/// becomes a `deletedAt` tombstone (a hard delete would come back from any
-/// member who was offline when it happened).
-///
-/// Conflicts resolve last-write-wins per document. Documents are small and
-/// granular — one per meal slot — so two people filling different days of the
-/// same week never collide.

-# Hogar compartido (2.2) — diseño
-
-Colaboración entre cuentas distintas y acceso desde Android. Issue #33.
-
-## Por qué no CloudKit
-
-El store es hoy `NSPersistentCloudKitContainer` (SwiftData con
-`cloudKitDatabase: .automatic`), que sincroniza la base de datos **privada** de
-un Apple ID entre los dispositivos de esa persona. Dos cosas lo descartan aquí:
-
-- No existe en Android.
-- Compartir entre cuentas exige `CKShare`, que SwiftData no expone (ya se
-  intentó en la 2.0 y se aparcó a la 2.1).
-
-## Arquitectura
-
-```
-                 ┌──────────────────────────┐
-  iOS / iPadOS   │  SwiftData (store local) │  ← toda la UI sigue leyendo de aquí (@Query)
-                 └────────────┬─────────────┘
-                              │  HouseholdSyncService (espejo bidireccional)
-                 ┌────────────┴─────────────┐
-                 │   Firestore (el hogar)   │  ← fuente de verdad cuando hay hogar
-                 └────────────┬─────────────┘
-                              │
-  Android / web  │  PWA (fase 2), lee y escribe el mismo hogar
-```
-
-SwiftData **no** se sustituye: sigue siendo el store local y el modo offline.
-Firestore es la fuente de verdad del contenido del hogar, y el servicio de sync
-mantiene ambos lados alineados.
-
-### CloudKit y Firestore no conviven
-
-Dos sincronizaciones sobre los mismos objetos se pelean — ya pasó con el sync
-por iCloud KV, y por eso existe `CloudSyncRuntime.isCloudKitActive`. Regla:
-
-- Sin hogar → como hoy: CloudKit activo, Firestore inactivo.
-- Con hogar → contenedor local (`cloudKitDatabase: .none`) y Firestore manda.
-
-El contenedor se decide en el arranque, así que al entrar o salir de un hogar
-la app pide relanzarse. Es un corte visible, pero la alternativa (dos orígenes
-escribiendo los mismos objetos, con ecos entre ellos) es una fuente de pérdida
-de datos.
-
-## Modelo en Firestore
-
-```
-users/{uid}
-  householdId, displayName, updatedAt
-
-invites/{code}                      ← resuelve código → hogar sin leer todos los hogares
-  householdId, createdBy, expiresAt
-
-households/{householdId}
-  name, createdAt, createdBy, memberIds: [uid], ownerId
-  members/{uid}          displayName, role: owner|member, joinedAt
-  dishes/{uuid}          name, descriptionText, tagIds[], ingredients[], isPriority,
-                         fixedDayOfWeek, fixedMealType, updatedAt, updatedBy, deletedAt?
-  tags/{uuid}            name, nameEN, color, reglas…, updatedAt, updatedBy, deletedAt?
-  weekPlans/{yyyy-MM-dd} weekStartDate, userRating, includeWeekendsOverride,
-                         mealTypesOverrideRaw, updatedAt, updatedBy
-    slots/{day}-{meal}   dishId, secondaryDishId, isEatingOut, isSkipped,
-                         isRuleOverridden, isRuleIgnored, updatedAt, updatedBy
-  shoppingItems/{uuid}   weekStartDate, title, dishId, isChecked, isDismissed,
-                         sortOrder, updatedAt, updatedBy, deletedAt?
-```
-
-### IDs deterministas donde importa
-
-Semanas y slots usan id derivado del contenido (`2026-09-14`, `5-dinner`) en vez
-de UUID. Si dos miembros abren la misma semana a la vez, ambos escriben el mismo
-documento en lugar de crear dos. Es la misma clase de duplicado que costó el
-crash de arranque de la 2.0, pero resuelta en el origen.
-
-Platos, etiquetas y líneas de la compra conservan su UUID: los crea una persona
-concreta y no hay id natural.
-
-## Conflictos
-
-Last-write-wins por **documento**, con `updatedAt` de servidor
-(`FieldValue.serverTimestamp()`) y `updatedBy` para poder depurar. La
-granularidad importa: el documento es el slot, no la semana, así que dos
-personas pueden rellenar martes y jueves a la vez sin pisarse.
-
-Los borrados son tombstones (`deletedAt`), no borrados duros: sin ellos, un
-dispositivo offline que no vio el borrado recrearía el plato al volver.
-
-## Alcance de la fase 1
-
-Dentro:
-
-- Cuentas (Sign in with Apple + Google) y hogar con invitación por código.
-- Sync de platos, etiquetas, semanas, slots y lista de la compra.
-- Desactivación de CloudKit al entrar en un hogar.
-
-Fuera, a propósito:
-
-- **Fotos de platos**: `photoData` va a `@Attribute(.externalStorage)` y un
-  documento de Firestore tope a 1 MB. Van a Firebase Storage en fase 2.
-- **Ajustes personales** (`AppSettings`): no se comparten. Idioma, horas de
-  calendario o estilo de export son de cada persona. Lo que sí es del hogar
-  (días y comidas planificadas) viaja en el propio `weekPlan`.
-- **PWA de Android**: fase 2, sobre este mismo modelo.
-
-## Premium
-
-Crear un hogar requiere premium. Los invitados entran sin premium — es el gancho
-del plan familiar, y quien invita ya paga. El resto de features premium siguen
-bloqueadas para el invitado.
-
-`isPremium` sigue viniendo solo de StoreKit y nunca se sincroniza, igual que hoy.
