Fix SCORM content blocked by CSP and X-Frame-Options

Browse source 
- Add 'self' to frame-src in CSP to allow same-origin iframes
- Add 'unsafe-eval' to script-src (SCORM packages often use eval)
- Add /uploads/scorm/ location that strips frame-blocking headers
- SCORM content served without X-Frame-Options or CSP restrictions
