ParticipantReport loadReport() to check reportType before loading saved configuration

[cnathe]

Rationale

ParticipantReport.js issue found by crawler running TimeChartDateBasedTest. When the ParticipantReport loadReport() takes the report id from the URL and loads the report config, it just assumes the report is of the correct type. However, if you give it a reportId for a different reportType, it will hit this JS error Uncaught TypeError: Cannot read properties of undefined (reading 'length'). This PR updates that loadReport code path to check for the expected ReportService.ParticipantReport before loading the config.
