feat(fusion_planning): add Employee Roles editor under Planning > Configuration

New menu "Planning > Configuration > Employee Roles" opens an editable
list of all active employees with two columns made for fast bulk
assignment:
- Default Role (m2o, fills new shifts automatically)
- All Allowed Roles (m2m tags, controls open-shift visibility)

Per-row inline editing with multi_edit enabled, grouped by department.
No wizard, no popup — set role per employee in one screen and move on.

Visible to planning.group_planning_manager.
