Add governance VAA test cases for SetFeeInToken, SetWormholeAddress, AuthorizeGovernanceDataSourceTransfer, SetTransactionFee, and WithdrawFee

- Added 5 new test functions following existing test structure
- Tests focus on Wormhole verification and instruction parsing
- Uses guardian address 0x7e5f4552091a69125d5dfcb7b8c2659029395bdf
- Note: Tests currently fail due to signature verification issues that need to be addressed
