Type Alias ObjectDotPaths<T>
ObjectDotPaths: { [K in keyof T & string]: Exclude<T[K], undefined> extends infer V ? V extends NonRecursiveLeaf ? never : V extends object ? DotPathKeys<V> extends infer D extends string ? `${K}.${D}` : never : never : never}[keyof T & string]
For a given entity, produces all dot-path keys for its ObjectAttribute fields. Checks each property: if it's a plain object (not a NonRecursiveLeaf), generates "propName.nestedKey" paths.
