update legacy-sdk

[jshiohaha]

Description

• Update the rest of the legacy-sdk packages to accommodate contract upgrade to Anchor 0.31 and Solana 2.1.0
• All of the changes here were manual and many are not different type names, so please review carefully. The reason that the events + accounts from PascalCase to camelCase changed is due to the whirlpools.ts that Anchor emits after building the program.
