Root cause of IllegalArgumentException is hidden in AdaptiveServlet when content policy has no widths configured.

Bug Report

Current Behavior

• configure the image component and don't set any widths in the content policy.
• when trying to access the servlet with any width the logs show the message:
  "Third selector must contain a valid width information (selector > 0)"
  The root cause of the exception is that the widths are not configured and there is an exception thrown that has the message: "The requested width is not allowed in the content policy or no default"

Expected behavior/code

• just if the message of the root cause would be displayed, it would be enough and easier to debug this.

Environment

• AEM version and patch level: AEMaaCS SDK 2025.9.22450.20250911T131210Z-250800
• Core Components version: latest
• JRE version: 21.0.8+9-LTS

Possible Solution

• adding the root cause to the exception thrown will suffice. PR incoming.
