Exclude project/projectId questions from agent setup journey

- Add explicit MUST NOT instruction: never ask about projects, projectId,
  or how to link records; project assignment is handled by the agent runner
- Remove projectId from template field list; remove projects from entity types
- Remove stale isApproved=0 reference (already removed from the data model)
