Maintenance

We ran into a small arithmetic bug with how liquidations work (using the requested liquidation size from the call message instead of the actual size that can be liquidated).
This led to some bad state in 2 accounts and the borrow lend USDC pool. For now that’s prevented users from creating new accounts.
We’ve patched the bug, and are deploying some fixes to hopefully rollback the problematic state today, so expect a few hours of downtime on the rollup.

Disable trace logging temporarily and separate out logs per environemtn

Major breaking change upgrade that requires a wipe of testnet:
* Improvements to efficiency and simplicity of margin calculations, should mean they are faster to compute and less bug prone
* Paving the way towards adding simulation utils which unblock important frontend metrics like estimated liquidation price on the order form (I know a lot of you have been asking for this)
* Important patches for subtle rust nondeterminism bugs which caused an outage the other day + some decimal rounding f...

Stability and minor improvements to testnet

Migrating sequencer and most backend infrastructure to Kubernetes. Bunch of important bugfixes around gas non-determinism, some more minor logical changes to performance and stability.
