Feature: #89978 - Introduce Status Report for insecure exception handler settings

See Issue #89978

Description

When using a debug exception handler in production (either by configuring it explicitly or by using the wrong application context) stack traces may disclose information. To avoid such setups a new status report has been introduced that warns administrators if a debug exception handler is configured.

Impact

To mitigate the information disclosure, a new status report has been introduced:

  • if display errors is set to 1 (-> uses DebugExceptionHandler setting) and context is Production, an Error is displayed
  • if display errors is set to 1 (-> uses DebugExceptionHandler setting) and context is Development, a Warning is displayed
  • if the production exception handler setting is configured to use the DebugExceptionHandler, an Error is displayed
