feat: Manage Workflow Groups via MDL

[kleineroscar]

Problem

Workflow Groups (configured under App > Settings > Workflows > Groups in Studio Pro) cannot be created, listed, or modified through mxcli. They are project-level settings — peers to UserEntity and DefaultTaskParallelism — but are missing from ALTER SETTINGS WORKFLOWS and DESCRIBE SETTINGS.

This blocks fully scripted project setup, since workflow user tasks reference these groups for assignment.

Workflow Groups are GA from Mendix 11.6 onwards.

Current State

ALTER SETTINGS WORKFLOWS
  UserEntity = 'Administration.Account',
  DefaultTaskParallelism = 3,
  WorkflowEngineParallelism = 5;
-- No way to define groups here

Proposed Syntax
-- List groups
SHOW WORKFLOW GROUPS;

-- Add a group
ALTER SETTINGS WORKFLOWS ADD GROUP 'Approvers' DESCRIPTION 'Primary approval group';

-- Modify a group
ALTER SETTINGS WORKFLOWS ALTER GROUP 'Approvers' DESCRIPTION 'New description';

-- Remove a group
ALTER SETTINGS WORKFLOWS DROP GROUP 'Approvers';

-- Include in DESCRIBE SETTINGS output for round-tripping

Why It Matters
Without this, developers must switch to Studio Pro to define groups, breaking automated scaffolding, CI/CD pipelines, and migration scripts.

Issue Triage

Summary:
The request is to add mxcli commands for creating, listing, and modifying Workflow Groups so they can be managed via MDL scripts.
