CloudFront Media Behavior Automation Web PHP v153

v153 fixes the Run controls and puts live run output directly inside the Run card below the buttons.

Run behavior

• Dry run and Apply are non-submit buttons.
• Dry run and Apply use a standalone AJAX streaming runner.
• The Run card contains an inline log panel under the buttons.
• Clicking a run button immediately writes a started line into the inline log panel.
• Streaming progress lines update the same inline log panel.
• Normal page POST is still blocked before CloudFront calls.

CloudFront behavior

• Apply/Dry run use the same AWS credential resolver as the green AWS credential test.
• JSON directory-index behavior is intentionally left untouched.
• Generated media behaviors preserve/restore default Lambda@Edge and CloudFront Function associations.
