When creating public links from federated shares, users should be able to set
the 'Hide download' option independently as long as they are more restrictive
than the original share permissions.
Previously, the `checkInheritedAttributes` method was ignoring user preferences
and always overriding the hideDownload setting based solely on inherited
permissions, preventing users from disabling downloads even when the parent
share allowed them.
This fix implements some sort of inheritance logic:
- Users can only be MORE restrictive than parent shares, never LESS restrictive
- If parent hides downloads -> child MUST hide downloads (enforced)
- If parent allows downloads -> child can CHOOSE to hide or allow downloads
- If parent forbids downloads entirely -> child cannot enable downloads
