Feat/mantine v7 update (#153)

* feat: upgrade to mantine v7

- this version removes css in js so a lot of the custom
  styling had to be rewritten
- theoretically it should be more performant than css-in-js
- also updated the rest of the npm dependencies

* fix: various analysis warnings

- remove unused stuff

* feat: various improvements

- replace framer-motion with autoanimate. the framer
  motion bundle was not great as we are only using
  a single animation for add / remove from lists
  in 3 components. autoanimate is less than half the
  size of framer
- add eslint config and fix any issues it reported
- import mantine css for just the components we are using
  - this saved >200 kb from the bundle
- fix some css issues to make it look like previous
  version
