chore: remove ReportPortal configuration (#3151)

The QA team has decided to remove Report Portal integration due to minimal
adoption and lack of tangible benefits. Developers rely on CI for test failure
analysis, and the Auto Triage feature was not utilized. Removing RP will simplify
CI pipelines and eliminate unnecessary maintenance.
