Reporting: Add interactive edit mode to Roadmap report

Editing capabilities within the Roadmap to make the Roadmap report a place to actively work on the Project portfolio and not just visualise it.

• Creation of new Fact Sheets directly on the report, no matter their hierarchy level

• Dragging of Projects along the Roadmap report to change their lifecycle phases

• Unlinking of Milestones from lifecycle phases (only for Project / Transformation Item Fact Sheets)

• Creation of dependencies between Projects / Transformation Items
