feat(shared-stores): add createArchiveOps factory + unify archive pattern

Standardize two-stage deletion across modules: archive (isArchived) +
soft-delete (deletedAt). Add shared factory, Archivable type mixin,
filterActive/filterArchived/filterNotDeleted query helpers. 13 tests.

Migrate memoro, chat, picture, contacts to use createArchiveOps.
Standardize picture from archivedAt timestamp to isArchived boolean.
Picture toggleFavorite now uses shared toggleField (1 param, not 2).
