New Aggregated Scorecard Tests

• Missing permission state: Validates scorecards show "Missing permission" message with 0 entities when user lacks permissions
• Manage scorecards: Tests adding/removing GitHub and Jira scorecard cards on Home page
• Entity counts: Mocks API with 15 GitHub and 10 Jira entities, validates pie chart threshold states using aria snapshots
• Empty response handling: Ensures scorecard cards are hidden when API returns []
• Threshold tooltips: Hovers on Success/Warning/Error states, verifies entity count and percentage in tooltips
