Bug fixes

• Issue #3444588: Switched from base_path to origin_url to fix issues when retrieving the path of the CKEditor plugins for use in a URL

fix: prevent total_turns reset when recording rewards and add experiment ID to page title

Refactored JS for recording individual turns for shown arms instead of recording all arms in a views display when the views display is in view.
This solves 2 problem:
1. Accuracy of recorded turns when not all arms in visible at time of recording turns

Fixed issues reports link not up to date with experiment uuid > id migration
Fixed 403 access denied issue with apache and rl.php, updated docs accordingly
