- Upgrade eslint and fix a massive number (~2500!) of linting errors from new rules.
- Upgrade babel core frontend dev dependency.
- Upgrade UI lib and other frontend deps.
- Refactor the Vue admin app to use `vite` instead of `webpack`.
- This was an extremely tedious and painstaking, trial-and-error
alchemy job. My disdain for the Javascript "ecosystem" grows.
- Re-add custom admin appearance endpoints to the refactored Vue page.
- Remove obsolete vue-cli config.
- Re-auto-format all .vue files again to work with new linters.
