Class TestRuntimeActionAction

Executes a Runtime action against one or more test cases and returns per-case pass/fail results. Used by ActionSmith before submitting an action for human approval — if any case fails, ActionSmith iterates with Codesmith to refine the code.

The action being tested can be:

• An existing Runtime action record (identified by ActionID or Name)
• A freshly-generated code payload that hasn't been persisted yet (Code + RuntimeActionConfiguration passed directly, no DB record required). This path uses a throwaway in-memory MJActionEntity with CodeApprovalStatus='Approved' so the executor permits it.

Test cases are evaluated in sequence; expected outputs (if provided) are compared to actual outputs with structural deep equality.
