Add blast-compatible prize pool extension

[trmid]

Extends the prize pool and adds the following:

• enforces that the prize token is the Blast WETH token
• opts-in to claimable WETH yield
• adds a function for anyone to trigger a donation of accumulated WETH yield into the prize pool

[linear]

GEN-1772 [114] WETH has automatic yield accrual on blast that is not handled in the prize pool

Looks good to me. Is the Prize Pool oversize now? It was so close before!

a part of me wonders if whether making this public would have incentivized people to "push the button", but this is a good solution too.

What if we called donateClaimedYield on new draws or something? Maybe that would automate it

I think every once in a while someone would come along and push the button just to see the GP number go up, but I'm not opposed to automating it either. The awardDraw function could be overridden to donate after each call, or the DrawManager on blast could be modified to do that as well.

The compile size is still good. Here's the build results:
