In https://jira.camunda.com/browse/OPT-3585, we added a new evaluate report by ID POST endpoint, to allow filters to be supplied. When the FE is using this for all evaluation of saved reports, we need to remove the old GET endpoint and associated tests.

ATs:

• The GET /report/reportId/evaluate  endpoint is removed, as are all associated tests against that endpoint (everything should use the POST endpoint instead)**
• Confluence API Docs are updated
