Show detailed diagnostics for 500 server errors

[Linda-Njau]

This PR improves how provider errors appear in the browser.

• Show detailed diagnostics instead of a generic 500 page
• Switch from raise Exit to raise exn so the original exception reaches the server handler
• Add e2e tests for 500 error pages

Hi !
Thanks for the contribution!
There is two missing part:

• https://github.com/Linda-Njau/yocaml/blob/server-error/plugins/yocaml_eio/server.ml#L62 there's also a server inside yocaml-eio
• a CHANGE entry :)

Thanks it is a valuable improvement!

The code looks fine to me, thank you, but I'd like to test the feature a little before merging :) I'll do that sometime next week (sorry!).

Thanks a million!
