[ci skip] Fix narrow iframe content and strip anti-debug scripts in proxy

Browse source 
- Remove flex centering from browser-viewer-content; use absolute positioning
  for iframe to fill the entire container
- Strip disable-devtool and devtools-detect script tags from proxied HTML
- Add JS shim hooks to neutralize setInterval-based debugger traps and block
  loading of anti-debug scripts via setAttribute
- Bump image to v1.2.5
