refactor(models): share control definition runtime fields

[lan17]

Summary

• Introduce ControlDefinitionBase for runtime-relevant control fields shared by authored and runtime control models.
• Move legacy selector/evaluator canonicalization and common condition/action validation onto the shared base.
• Keep template metadata and template pairing validation only on ControlDefinition, while ControlDefinitionRuntime keeps runtime parsing with extra="ignore".

Why

This addresses #200 by removing duplicated runtime fields and validators between ControlDefinition and ControlDefinitionRuntime, making future root-level runtime fields easier to add once.

Validation

• make models-test
• make lint
• make typecheck
• make check

Fixes #200
