Create ProjectRiskScorePanel
## TL;DR
Create new component ProjectRiskScorePanel for the project level risk score panel, inspired by GroupRiskScorePanel. We can cut a lot of the functionality within that group-level component:
1. No url param sync for the group by
2. No group by buttons or variables passing to query
3. No per project risk score chart
4. No max projects badge
## Implementation Details
1. Add ProjectRiskScorePanel component, inspired by GroupRiskScorePanel
2. Compared to GroupRiskScorePanel we should remove:
1. URL param sync and init for group by param
2. Passing `includeByDefault`, `includeByProject`, `first`, and `projectId` variables to GraphQL query
3. Parsing `byProject` from GraphQL response
4. Projects count threshold and showing a badge with max projects shown
5. Group by toggle button
6. By project component in template
3. Add new GraphQL query `project_total_risk_score.query.graphql` based on `group_total_risk_score.query.graphql`
4. Add tests
