UI Suggestion: Network Hashrate Chart Adjustments #1987

As we know, the PoW hashing algo change around 9/1/2023 massively altered the network hashrate. To people not in the "know" about Decred, it looks like the hash-rate straight up died. This is really bad optics, and it's something I've had people ask me about repeatably.

I don't know the direct solution as this isn't my field, but I humbly request this be given priority attention for the sake of optics and network health to the outside world. (I might add all of our other charts look brilliant.)

Thanks.
