Rework types for logic function (#18074)

## Summary

- **Consolidate logic function services**: Remove
`LogicFunctionMetadataService` and consolidate all logic function CRUD
operations into `LogicFunctionFromSourceService`, with a new
`LogicFunctionFromSourceHelperService` for shared validation/migration
logic
- **Introduce typed conversion utils following the skill pattern**: Add
`fromCreateLogicFunctionFromSourceInputToUniversalFlatLogicFunctionToCreate`
and `fromUpdateLogicFunctionFromSourceInputToFlatLogicFunctionToUpdate`
that convert DTO inputs directly to flat entities
(`UniversalFlatLogicFunction` / `FlatLogicFunction`), replacing the
previous intermediate `UpdateLogicFunctionMetadataParams` indirection
- **Simplify `CodeStepBuildService`**: Remove ~100 lines of manual
duplication logic by delegating to
`LogicFunctionFromSourceService.duplicateOneWithSource`
- **Remove completed 1-17 migration**: Delete
`MigrateWorkflowCodeStepsCommand` and associated utils that migrated
workflow code steps from serverless functions to logic functions
