## Summary
- Fixes a regression from #20208 where creating a new CODE workflow step
shows no input fields
- The split-triggers PR removed `SEED_LOGIC_FUNCTION_INPUT_SCHEMA` and
replaced `toolInputSchema` with `workflowActionTriggerSettings`, but
`CodeStepBuildService.createCodeStepLogicFunction` was not updated to
pass the seed schema — causing `logicFunctionInput` to default to `{}`
and no fields to render
- Adds `SEED_WORKFLOW_ACTION_TRIGGER_SETTINGS` constant (matching the
seed template's `{ a: string, b: number }` params) and passes it when
creating the seed logic function
## Test plan
- [x] Unit test updated to assert `logicFunctionInput` contains `{ a:
null, b: null }` on code step creation
- [x] Create a new CODE step in the workflow builder and verify input
fields `a` and `b` appear immediately
