Fix formula files for bd cook compatibility (gt-8tmz.3)

- Add required title fields to shiny.formula.json steps
- Add required title fields to rule-of-five.formula.json template steps
- Fix shiny-enterprise.formula.json schema: use compose.expand array format
- Add type: "workflow" to shiny.formula.json

These changes align formulas with the expected schema in bd cook.
