Extend aiInsightResponseSchema with weeklyReport (ISO week + summary +
goingWell/worthWatching/tips bullets + optional dataQualityNotes) and
storyboardAnnotations (date + label + category + detail; max 20).
Both blocks are nullable + optional so legacy 4.20.1 caches round-trip.
Bump PROMPT_VERSION 4.20.1 -> 4.20.2 and add GROUND RULE 10 (weekly
report sections match layout, conservative phrasing, no causal claims)
+ GROUND RULE 11 (storyboard annotations are factual user-logged events
with neutral prose) to both EN and DE prompts.
