Simplify vite config in templates

[dk1a]

Now that #328 is merged, after it's published it may be worth checking whether the verbose exclude+include are still necessary in templates vite.config.ts
(waiting for publish is useful since some issues aren't apparent when linking locally)

Looked into it some more, apparently services lacking dependencies was a minor issue.
The bigger one is that vite's optimizer doesn't support the way we use webworkers:
vitejs/vite#11943
vitejs/vite#11672
Not sure about vite internals, but since it uses esbuild this PR might make it work:
evanw/esbuild#2508
