Lock decision edge cases with business state tests

The dashboard risk is now mostly contradictory state combinations rather than styling. This extracts calendar action grouping into a pure utility and adds a lightweight TypeScript business-state runner so key decision states can be asserted without adding a test dependency. Constraint: No new dependencies; use the existing TypeScript package for a local runner. Rejected: Only rely on Next build/typecheck | it cannot catch product-language regressions such as fallback AI being labeled complete. Confidence: high Scope-risk: moderate Reversibility: clean Tested: npm run test:business Tested: npm run build Not-tested: Browser-rendered mobile fold interaction snapshots.
