Perps V3: Update subgraph

[Tburm]

Update the subgraph to include:

• Match the latest testnet deploy
• accruedFunding on the OrderSettled event
• Index the PreviousOrderExpired event
• Index the CollateralModified event

Note: Since the function signatures changes, we will be missing OrderSettled events from before the deploy on August 14. Since there is not mainnet deploy of the old version it shouldn't be necessary to handle both signatures.

LGTM

@Tburm we can have subgraphs for multiple networks (see #1784 or just look at new structure of synthetix/subgraph)
I planned to update spot/perps subgraphs too after your PRs are merged.

@noisekit Looking at your PR, I think that will be really useful to split by network. I've already run into some conflicts as we add things to the contracts and deploy to cannon -> testnet -> mainnet where a flow like this will help a lot.

Great. I will do similar update to perps then. Also if you give me an exact example we have conflict now that I can ensure is also resolved along the way - that would help. Want to ensure new structure allows us to deal with such issues in the least annoying way possible

@noisekit I think the contracts are currently in sync with cannon and OP Goerli, so likely no conflicts. We haven't changed any events since the last testnet deploy.
