fix: add view modifier to pure assertion test functions

- Add view modifier to test_Initialize() in DstackApp.t.sol
- Add view modifier to test_SupportsInterface() in DstackApp.t.sol
- Add view modifier to test_Initialize() in DstackKms.t.sol
- Add view modifier to test_SupportsInterface() in DstackKms.t.sol

This resolves Solidity compiler warnings about function state mutability
and makes the code more explicit about which test functions only read state.
