feat: update error page

[KevinWu098]

Summary

1. Restyles error page for mobile
2. Updates error display to use an Accordion
3. Display current route

Test Plan

1. throw an Error somewhere, somehow (easiest may be to pull locally and manually throw)
2. Check error page on desktop, confirming readability and that error is displayed by default
3. Check error page on mobile, same considerations as desktop (especially responsiveness & readability)
4. Check error page on light and dark mode

Issues

Follows up #968 and #1035

(I should've caught this originally on #1035, that's my bad)

Seems about right
