crypto: api - use designated initializers for report structs

Use designated initializers for the report structs instead of clearing
the struct with memset() and then copying fixed strings with strscpy()
at runtime.

This keeps the structs zero-initialized, lets the compiler diagnose
oversized string literals, and makes the code easier to read.
