[Code health] Submission panel inverse logic and "componentization"

[rfontanarosa]

• Invert logic in SubmissionView (iterates over submission data instead of tasks) to preserve collection order
• The view visualization of various task types should be componentized
• A lot of logic is exposed in the template and it should be moved in the component (e.g. how the URLs are stored in the component, how we get the result for a task, how we extract the value)
