Gusted c8ec9bc2cc feat(ui): lazy-load all Vue components (#9444)
Some Vue components were already lazy-loaded, but not all.

There are three main changes:
1. Move init scripts outside Vue code.
2. Make the init scripts lazy-load the Vue components.
3. Deal with vue linters, because apparently if you do `export default` then some Vue linters will notice that's vue sfc.

The rationale for this pull requests is that this reduces the size of the `index.js` file.
- Uncompressed: 1.24 MB -> 954.40 kB
- Compressed (gzip, via `reverse_proxy` of Caddy): 400.45 kB -> 298.95 kB
- Compressed (zstd, via `bindata` tag): 363.75 kB -> 274.22 kB
