feat: cross platform page system

[IMB11]

Currently this is only going to be used by the servers pages, but I dont see why we cant use this for orgs, users, collections etc.? Out of scope though

• Sets up @tanstack/vue-query which is a cross platform useAsyncData alternative - this will only be used in the @modrinth/ui package and potentially the app frontend in the future?
• Set up a system inside of @modrinth/ui for automatic page registration on nuxt + app frontend
• Migrate server list page as an example of usage
• Moves api client DI context to @modrinth/ui.

Places to look:

• packages/ui/src/pages - I tried to make a dynamic page system, however i was running into issues with nuxt, so I think it's probably just easier to just create stubs on the frontend, this isn't great... For the app-frontend we can just pass the page from @modrinth/ui into the route object in the routes.js, which is good.
• packages/ui/src/pages/servers/manage/index.vue - Take a look at tanstack query, it's a cross platform useAsyncData alternative (that's actually better in most cases) - read more: https://tanstack.com/query/latest/docs/framework/vue/overview
• packages/ui/src/providers/api-client.ts - abstracted
