feat(sprint-4/etapa-5): modelo de privacidad RLS granular + UI de visibilidad

- SQL 010: tablas user_groups y group_memberships con RLS
- SQL 011: tabla process_access para acceso explícito a procesos
- SQL 012: función is_platform_admin() + políticas granulares (select/insert/update/delete) en processes
- types.ts: Process.ownerId (requerido)
- process-repo: fromRow mapea owner_id→ownerId; toRow preserva ownerId en updates; setShared() no-op documentado
- ImportPage: asigna ownerId: user.id al crear proceso
- LibraryPage: toggle Todos/Míos, OwnershipBadge (🔒/👤) en cada tarjeta, opción "Compartir con equipo" en menú de proceso propio con toast de confirmación
- Tests: ownerId: 'test-user' agregado a todos los fixtures de Process
