[Frontend] Tree page - functionality

[BearDimonR]

Try to use d3 lib to make tree like here: https://2-dot-sb-tree-app.appspot.com/#/

Checklist

• tree page render tree nodes
• data for tree retrieved from backend database (not from json)
• card design show all necessary information (who is, status, etc.)
• tree renders normally with realistic data (if i can easily find myself) (related to [Data] Collect realistic data for deployment and tree implementation #9)
• functionality (i can find person i want (search), i can find its children and parent)
• performance (try to mock ~100 nodes, need to fix lagging)
