Adds @emotion/styled, icons, and changed table header

[fishcodeslol]

Doing updates in small pieces for issue #5

• adds @emotion/styled, a few icons in <Icon />, and changed table header
• adds an "All" requests tab

Note: I'm still looking for a good icon set and the ones grabbed just acts as a placeholder for now

Q: Was there a reason why you didn't try to use the component on mantine? Was doing a custom table/expand just easier? @LordZesus
