[Planning] Partner Self-Service Tooling

### Objective
Create the initial plan for the **Partner Self-Service Tooling** epic. This includes:
- Defining scope and success criteria
- Identifying key deliverables and milestones
- Mapping dependencies and risks
- Proposing an implementation approach
- Identifying stakeholders and owners
