Firstly as far as I know the panel does not need GFCI and if it did you wouldn't want it on the outlet as when something trips the outlet your panel is dead.

When you say "dead," do you mean unpowered until the GCFI is reset or do you mean the GCFI getting tripped will damage the panel?

Thanks for the clarification. Yeah, that would not be a long-term solution but I was hoping it might be better than the piggyback power the board is currently getting. It might be some days before I can get my electrician friend out to look at the panel so I was hoping to find something I can do myself in the meantime.
You can use the connection from the "line" side of the GFCI to power the panel with no issues. There should be one available on the device.
Thanks! I already have a line running from that GCFI outlet to the panel (for a stenner pump) and now that I'm home, I was able to trip the GCFI and found that power was still going to stenner pump so the wiring must not run through the GCFI like I originally assumed.
Here's a pic of my CB panel. Breakers 6/7 currently power the Oasis panel, filter pump and booster pump. 9a powers a GCFI outlet, pool light and stenner pump.

You or an electrician can tap in to the non-GFCI side of 9A and power your panel from that CB.
Breaker 6/7 should be changed to GFCI for your pumps.

Awesome, thank you!
So 9a already runs to the controller for the stenner pump. Should I used that to power the board instead and if so, can I power the stenner with a piggyback from the pump relay?

You can power the Stenner and the panel.
Connect the panel wire to the LINE side of the Stenner relay to pickoff the power from the same CB.
Done! Thanks again for your help with this. I've just got to get the GCFI breaker installed now and then I should be good to go.
On a side note, I noticed that the filter pump relay is always on. I asked Waterway and they said that was normal because I have a variable speed pump which always needs power. My booster pump is powered from the load sides of the filter pump relay and I had thought this prevented the booster from running without the filter pump but now I see that is not the case (since the load sides of the filter relay are always powered). In this scenairio, is there any feasible way to ensure the booster pump only runs when the filter pump is running?
Oh wow, that's super helpful.
Looking over the various threads on that topic, it seems they're all for 120V SWC but if I'm understanding correctly, this diagram should work for my 230V booster pump?

That diagram is dangerous leaving L1 always hot. Someone working on the pump may assume with the pump not running there is no power to the wires.
The NEC states both legs of a 240 volt circuit must be switched together.
Thank you, I was actually wondering about that after I posted my reply. Wasn't sure what would happen to the booster if its relay turned on without the current switch engaged sending only one leg of the 240V to the booster pump. Whatever would happen, I'm guessing it wouldn't be good for the pump?
That relay is supposed to support 240V so I wonder if there's another way to wire it so that it switches both legs.

Pentair, Jandy, and Hayward automation systems can set a cleaner pump relay so it only is turned on when a VS speed is sent to the filter pump. I am surprised that the Waterway system does not handle a cleaner pump.

One leg of the 240V circuit is always powered in that diagram. It does not matter if the relay is turned on.
Those diagrams and switches come from overseas vendors who don’t care about safety.
You need to find a CSR that is a double pole relay, not the inexpensive single pole relay, that switches both legs. And the relay must be able to handle pump amperage.
