CloudFront Media Behavior Automation Web PHP v152

v152 fixes the AJAX-only run controls. Dry run and Apply are now non-submit buttons and call the streaming AJAX runner directly. They no longer depend on form submit interception.

Safety behavior

• Dry run and Apply buttons are type="button".
• Dry run and Apply call ajax-run-action directly.
• Normal page POST for Dry run / Apply remains blocked before CloudFront calls.
• Each run requires a fresh action token from the current rendered page.
• The action token rotates immediately when the run starts.

Progress behavior

• Apply/Dry run stream newline-delimited JSON progress rows.
• The result panel updates as progress rows arrive.
• The browser receives output during the run instead of waiting on a silent spinner.

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.
