fix(reports): move new contributor badge to bottom-left and update demo

- Move badge from top-right to bottom-left to avoid blocking username
- Update January report: rwaltr and istvan-derda as new contributors
- Remove tulilirockz from new contributors section

The badge now appears in the bottom-left corner where it won't interfere
with the name, bio, or stats content.
