34039551 - [test] Use unique error messages in `server-source-maps` (#79108)

[test] Use unique error messages in `server-source-maps` (#79108) Allows unambigious assertions on CLI output. Not that interesting for dev but `next build` will have the logs for all pages in all tests. I also made the pages static where possible so that we'll be able to assert on the logged errors during `next build`.
