Change build to use Vite and Typescript

[C-Loftus]

This code does not add any new user-facing behavior and should hopefully not be too hard to review. I kept the same overall components and layout of the codebase since I think it is well thought out.

Before review, goal is to:

• fix all existing eslint errors. i.e:
  • Get rid of v-html which can be insecure
  • Remove const self = this and any places where this is shadowed
  • Reduce global variables. Put all necessary global variables into a pinia store instead of mutating global this
  • Refactor functions which mutate parent props
• switch off old dependencies to current vue standards (pinia instead of vuex etc)
  • I am only switching dependencies that have a recommended updated version. (i.e. vuex vs pinia). Otherwise I am keeping things the same.
  • Allows us to no longer need to use --force or --legacy-peer-deps
  • I am not adding any extra dependencies except ones that are a better supported version of an old one
• switch to vite instead of webpack
• update dockerfile
  • current dockerfile uses node 14 which is very old
• switch to typescript instead of js
  • Realize that this is a significant change and if others feel differently, please feel free to let me know.
  • I have caught some current issues through this (mainly wrong types for vuetify like passing in a string vs number) and think it is worthwhile
• add some tests and interfaces so we can feel more confident when doing some of the json

@C-Loftus. It appears there is something wrong with setting the environment variables in the Docker deployment. I am able to work around this by not setting any variables at root level:

Additionally, the UI displays a weird error when there are no observations published from a station.

Thanks for catching that @webb-ben
I will investigate that, fix it, then rerequest your review before others look.
