What's changed and what's your intention?

to make HTTP API returns status code, I changed the returning value of ErrorResponse::into_response and map code to StatusCode. Here is the returning mapping:

Success, Cancelled ==> OK(200);

Unsupported, InvalidArguments, InvalidSyntax, RequestOutdated, 
RegionAlreadyExists, TableColumnExists, TableAlreadyExists, 
DatabaseNotFound, TableNotFound, TableColumnNotFound ==> `BAD_REQUEST`(400);

PermissionDenied, AuthHeaderNotFound, InvalidAuthHeader, 
UserNotFound, UnsupportedPasswordType, UserPasswordMismatch, 
RegionReadonly ==> `UNAUTHORIZED`(401)

AccessDenied ==> `FORBIDDEN`(403)

Internal, Unexpected, Unknown, StorageUnavailable,
RegionNotReady, RegionBusy, RateLimited, RuntimeResourcesExhausted, 
PlanQuery, EngineExecuteQuery ==> `INTERNAL_SERVER_ERROR`(500)

I also changed some test code to match these status code.

some code may need to be changed on front-end(like dashboard) to handle these error code
