Industry-specific validation rules

### Description

**As a user in a regulated industry**

**I want to be advised on ensuring that my flows meet mandatory standards**

**So that I can use FlowFuse for my most critical applications and easily stay in compliance**

Several industries (especially regulated industries) require certain standards to be upheld, and for documentation of this to be provided. We can build validation rules that can be run by the user, or at least provide guidance on flow building practices that satisfy such rules in app.
