So... I have larger questions about this:

How was this not an issue from the start? If you have a 2x4 structural wall (any outside wall) you aren't going to make a horizontal run of drain pipe through more than a stud... possibly 2. Definitely not through the jack and king studs if there's a door or window (and sinks often go under a window) because it weakens that too much. This is 100% foreseeable.

Through the floor (perhaps into the wall and through the bottom plate) is fine as long as there's a basement or crawl space.

But the other issue is the venting. How is this venting? My guess is that venting wasn't considered. I can't see the entire distance, but I think you are already too far from the old vent. And are what we are seeing the intended slope? Look, the drain and venting needs to be figured out by someone who knows what they are doing.

These kinds of issues need to be sorted on paper - way before anything gets torn out. There are enough surprises when you open a wall, and obvious ones that you could foresee shouldn't be one of them. This is one of the ways that jobs go bad... that things aren't planned out and then significant changes need to happen mid-project. The customer starts getting pissed, and suddenly the relationship goes sour. It's a lot better to be able to say up-front, "we can't move that sink there without doing x, y, z" and manage expectations than it is to do it on the back-end.

Is the DW not right net to the sink? Because it drains into the garbage disposal or a DW stubout on the sink, above the P trap. It MUST be above a P trap, to prevent backflow.

If you have room, pull you cabinets forward and install them in front of that pipe. Your countertop will have to be deeper to cover the gap between the cabinets and the wall but you will appreciate the extra depth. We had to do that once to accomadate a gas pipe and it was nice to have the countertop be 2" deeper. In our case we had to have a cabinet end panel made 26" instead of 24 to also cover the gap.

This was self designed disaster and no pros were involved prior or current.

Yeah, that's my thinking also. Too often homeowners want to "play GC and designer" for a job, either because they don't know any better or because they think they can save a few bucks. A decent GC can often do a passable job on a simple kitchen remodel if they don't get into high-end finishes and such, but a designer makes a huge difference. A homeowner who has seen it done on TV and thinks that's they can run a job is a slow-motion train wreck waiting to happen.

Homeowners don't know what they don't know. However, the contractor doing the work should. They are in a position to know when a homeowner intends, either knowingly or without realizing, to take on the GC role. Best to clarify the roles and responsibilities up front and get agreement, or walk away and not take the job.

I've made a similar comment on here before about homeowners assuming the role of GC - until something goes wrong - and then then it's all the contractor's responsibility.

Your contractor is correct as is badgergal. I've had to pull cabinets forward to accommodate drain lines. The deeper countertops are a feature, not a bug.

I'd also look into just having some of those cabinets built 2 in shallower. Most cabinets are being built to order anyway. It wouldn't be all of the cabinets, just those.
