[ci skip] Fix video playback and comprehensive anti-debug neutralization

Video:
- Add allow="autoplay; encrypted-media; fullscreen" to iframe for media playback

Anti-debug:
- Strip ad/popup scripts (acscdn, popunder) and context menu blockers from HTML
- Strip debugger statements from inline HTML scripts and proxied JS responses
- Intercept setTimeout (not just setInterval) for debugger-based detection
- Override eval() and Function() constructor to strip debugger statements
- Bump image to v1.2.6
