Give it a sand and see, looks like lots of loose bits that will easily come off.
I recently used lining paper and regret it. Wish I'd paid extra for a skim. Reason being seems are noticeable and in some places lifting after painting :(
If you're going to finish off with a thicker vinyl washable paint, I'd go with a cheaper but still good option of Leyland Trade.
Lots of the wipeable paints now come in matt so no need to use eggshell. Dulux Easycare is very good, there is a good comparison here of paints you can wipe.

I would expect some difference due to the reflective finish of satinwood but nothing like in your picture.
I expect it's clearly visible even just in the tin?

This, the only way you will know what is reasonable for your area to get at least 3 quotes. The more the better. Though don't go with the cheapest, go with who you think would do the best job.
Some of the cracks look pretty big, do they extend to the outside?
If the house is moving a lot over a year, I'd board otherwise you're going to get cracks again sooner or later.
I usually buy cheap paint and have no issues. Decided to buy Dulux Diamond for the hallway as likely to get marked so can wipe, it's really patchy when daylight hits certain walls, gutted. The paint is really thick, but don't understand why this is patchy and cheaper paint isn't it. I'm not...
