feat(database): support uuids as primary columns

[innocenzi]

Closes #619

This pull request adds support for generating UUID v7 primary keys during insertion. Note that since IsDatabaseModel provides a id property, which cannot be extended to receive the #[Uuid] attribute, this feature is technically not compatible with IsDatabaseModel.

final class User
{
    #[Uuid]
    public PrimaryKey $id;

    public function __construct(
        public string $name,
    ) {}
}
