fix(notifications): health attribute path + deterministic band conditions

- Fix MeshHealth.score.composite path (was accessing wrong object)
- Add deterministic band condition calculator from SFI/Kp/time
- RF reports use structured band format, not LLM
- Fix LLM prompts for health/weather reports (max_tokens, format)
- Graceful handling when data sources not configured
