This feature doesn't make much sense to me. It looks like you're trying to take a workflow run from seqera cloud and run the same pipeline locally. But then you need to make sure that the pipeline can be launched in the local environment with the requisite inputs, etc. It might work out-of-the-box for the hello pipeline but not a real pipeline.

You might need to go back to the drawing board on this one.

@MythicalFish if you want to trim this PR down to the UI refactor (or make a separate PR) I will merge that

Ok sounds good. Rip it out for now and just keep the bug CSS fixes in. @MythicalFish

this is good to merge from my POV. lmk @bentsherman
