Pull request overview

Updates the generic Diagnostics page e2e spec to be more stable in CI by integrating Qase IDs, tolerating known focus-trap-related uncaught exceptions during download modal close, and cleaning up downloaded artifacts between tests.

Changes:

• Wraps the diagnostics download test with qase(1454, ...) for Qase reporting.
• Extends uncaught:exception filtering to ignore additional “tabbable” errors associated with the focus-trap modal behavior.
• Adds an afterEach cleanup step to remove the downloaded diagnostics JSON.
