Improvements to candidate view

We have rewritten most aspects of the application views that are used by candidates while apply to the job.

• Countdown timer before recording starts. Shows a 3,2,1 timer by default now

• Formatting fixes on job description. Job descriptions now show the formatting applied to the text

• Job descriptions can have code external media embedded. Externally hosted media like videos and presentations (and even full websites) can be embedded inside the job description using the iframe button in the editor toolbar in the job description section.

• The video/audio/screen recording answers can now be entered right below the question. In case the question has a long description or embedded media - an "Answer" button now shows which can scroll the candidate smoothly to the response section below.

• The recording start and stop button is now placed right on top of the video / audio - to reduce the space needed below. This is to fix reports from some candidates who could not find the start recording button.

• We now have a 3 second countdown on all video/audio recordings before recording is started. The timer UI has been improved - and an element has been added to show that a recording is in progress.

• Similar improvements to the audio response questions as well.

• The retake and next buttons have been made bigger. A back has been added to let candidate modify the previous answers (if they have retakes available for those)
