* Account size: Don't fail on unrelated resize
If the account was previously resized to larger than is allowed now,
don't fail unrelated resizes.
* Further reduce account size limits
Out of caution and future-proofing. Can always raise again.
Perp settle pnl needs 6 accounts plus 2 health account lists that could
be nearly fully disjoint.
Users can request token swaps to happen when the oracle price
is within a price band. Once the price is right, an executor can
trigger the swap. The executors are rewarded with a premium
over the oracle price.
This allows limit and stop loss orders on arbitrary spot pairs.
The PR comes with basic ts support and adjustments to the liquidator,
to execute available token conditional swaps.

This changes perp market margining to no longer assume all pnl is in USD
while settlement is in USDC. Instead, a configurable settle token is used for
pnl and settlement, defaulting to USDC.
There is no difference while the USDC price is forced to $1 and the init and liab
weights are 1. But with this patch, it becomes possible to change that.
For now it is not recommended to use a token other than USDC or USDT (or
another USD targeting stable token) for perp settlement.
The patch also updates all insurance vault use to be aware that the insurance
fund is not in USD but in USDC and apply the USDC price before payouts.
To do this, the previous PerpLiqNegativePnlOrBankruptcy was replaced by
a new PerpLiqNegativePnlOrBankruptcyV2 instruction.

* liquidator: Don't attempt to close in-use token positions
This could happen if the user manually used serum on the liquidator
account.
* Client: Move jup's CU ix outside of flash loan
That makes a flash loan based jup swap usable with delegates.
* Fix bug where if no insurance fund position was present, ix would error out

It looks like it wasn't possible to exploit the program by
re-initializing the user-owned token accounts used in flash loan because
the later use of health_ais with the health computation would error out
if any token account was included there.
However, the check and a few others were too indirect. In this patch:
- We pass the number of loans into FlashLoanEnd explicitly (verified
from FlashLoanBegin)
- Add explicit checks for token mints, so it's no longer possible to use
token accounts for foreign mints in Begin when the loan amount is zero,
and it's clearer to see that the bookkeeping in End won't break if the
user reinited the account for a different mint.
- Also add a few other extra comments and checks.
The updated FlashLoanEnd instruction is called FlashLoanEndV2
