What is the issue you are experiencing?

As you can see in source code here...

This request isn't honoring the NUXT SUB_PATH variable..

mealie/frontend/plugins/theme.ts

Line 23 in 93c2df4

const route = "/api/app/about/theme";

So if you're running MEALIE under a SUB_PATH (just like myself - and many others.. #695 ) this API call will always fail..
(hit a 404 endpoint)

Steps to Reproduce

1. Build Mealie with SUB_PATH="/mealie123/"
2. Open the site under.. http://localhost:9000/mealie123/
3. Open the browser's network tab
4. See the theme endpoint fail (/api/app/about/theme)
5. It should be /mealie123/api/app/about/theme

Please provide relevant logs

/api/app/about/theme --> 404
