refactor: update createSessionKey function to remove contract parameter

- Remove contract input parameter from createSessionKey function
- Recreate contract internally using account.address and MinimalAccount ABI
- Update function signature to take client and chain directly
- Update tests to use new function signature
- Set ABI to MinimalAccount contract ABI as specified
