**Runtime Upgrade #1026**

- InterestAccrual V2: This updates pallet-interest-accrual to store all rates in a vec, rather than in an array. This makes rate accrual and nav updates much faster, at the cost of slightly slower rate lookup for operations on individual loans (borrow, repay, write-off)
- Loans refactor: Remove pallet-loans storage and replace the pallet with `pallet-loans-ref
- PoolSystem: Remove duplicate metadata hash from pool-system
