fix: all iOS compile errors - protocols, missing fields, colors, shadowed max

- Protocol conformance: list→listAll with extension defaults
- ContinueLearningResponse has no lastPosition→use nil
- LearningSession has no readingTargetType/materialId→use defaults
- Color.zxBlue→Color.blue, Color.zxIndigo→Color.indigo
- Shadowed max parameter→Swift.max
- ForEach Identifiable→explicit id: \.id
