Add stepper to reports configuration page

[HeleenSG]

The current report configuration page is missing a stepper.
Recently, a new stepper is introducted (#2394 and #2704 ) which should also be implemented at the top of the config page with the following steps:
1: Select objects
2: Choose report types
3: Configuration
