Generates a Resource.Form helper module at compile time for every resource that declares one or more forms in forms do ... end.

The generated module exposes one function per declared action:

• for_<action>/1 for create / read actions
• for_<action>/2 for update / destroy actions (record + opts)

Plus introspection helpers:

• actions/0 — list of declared action atoms
• schema/1 — schema for the given action
• nested_forms/1 — AshPhoenix.Form :forms config for an action
• required_preloads/1 — relationships to preload when editing
