QA: Show most information fetched from DB and refactor code
This MR shows most of the information fetched using the existing DB query.
Future improvements could include:
- Using i18n inside Genshi templates to simplify code.
- Sorting packages by urgency using a score computed using all of the failing conditions and popcon.
- Presenting information with better layout to help contributor pick tasks easily while optionally showing more advanced information.
- Styling improvements for consistency with Debian theme, modern look and a mobile device compatibility.
