FE: Resolve "Performance issues when processing large build traces with Ansi2html"

What does this MR do?

Frontend adjustments to:

• match new API
• match new design
• reduce code complexity

Decisions taken with @ayufan :

• We just need to make one request.
• No need to verify the state and the status anymore before doing the request
• Indication that we should make the request again is given by last response - complete key
