Newton's First Law isn't the same as the conservation of energy. It's related to it, but it's not the same. And again, red-shifting is a behavior, not a law. There is the Hubble-Lemaitre Law, but that's not the same as red-shifting. You are being bamboozled because someone is teaching you to conflate and confuse words and meanings.
"The story of existence" isn't defined by Newton's laws. Newton just created a system to explain kinematics by identifying it's simplest component parts. That system has held entirely true. We already know where Newtonian Mechanics falls apart, which is why Einsteinian Mechanics and Quantum Physics exists, but those fundamental laws do not actually change. It's only that the math context and assumptions Newton was using aren't sufficient.
The energy of galaxies is not red-shifted. The light is. That's because it's moving away. The wavelengs of the light are increased because it's moving away, that's why it's red. That doesn't have anything to do with the energy state of an object.
Yes, Energy is conserved on the scale of the universe. That would be the perfect conservation. It doesn't have a non-universe to go to.
It’s clear that cosmologists have not done a very good job of spreading the word about something that’s been well-understood since at least the 1920’s: energy is not conserved in general relativity. (With caveats to be explained below.)
So where is the energy that was once contained in the photons after the photons have been redshifted?
Graph, they didn't go anywhere. It's the same photons.
If the wavelength shortens, it gets more "blue" because that's the color of light with a short wavelength. If the wavelength lengthens, it gets more "red" because that's the color of light with a long wavelength.
The photon is still the same light. It's Doppler Effect of light.
If a car drives towards you, the engine gives a higher pitched noise because that's the wavelength of sound with a compressed wavelength. When it passes you, it gives a lower pitched noise because that's the wavelength of sound with a lengthened wavelength. But within the car, the noise is always the same.
Sound wasn't lost when it passed you going from high to low pitch. The wavelength of the sound changed.
You are being bamboozled. Literally.

It’s okay to admit you don’t understand Hubble redshift, you don’t need to project out your intellectual insecurities onto others.
Energy is not conserved on the scale of the universe. Where do you think the energy being redshifted is going?

You might think this sounds silly but it’s only because you haven’t thought/read about the subject enough
Here is cosmologist Sean Carroll:

The redshift (or blue shift) is no different.
