Deactivate frontend caching via the backend

[SteveMicroNova]

What does this change intend to accomplish?

Deactivates caching of the frontend css and javascript files to avoid users being stuck with stale code, particularly fetch requests that no longer match backend endpoints

Will require users to clear cache one time post release but never again afterwards

How was this tested?

I can see the hashes for the javascript and css bundles are when refreshing the frontend (see image) so I could see when they did or didn't change as I made changes to javascript before redeploying.

Before this change, the hash was the same every time unless deactivating my cache, after deploying this and deleting my cache it changed with every new deploy as it's meant to.

Can you validate this works on android/ios as well.
