Returns a deterministic string representation of an enum value. For enums with alias members
(multiple names sharing the same underlying value, e.g. Default = 0, Success = 0), the
built-in ToString() picks one of the names in an implementation-defined way
that can vary across .NET runtimes. This method returns the alphabetically-first preferred
name among aliases — names marked [Obsolete] and the literal name
Default are deprioritized and only used as a fallback when no preferred alias exists,
so diagnostic messages and log output stay stable.
