Photo and gallery rights

In Harmixo, rights should be understandable: who may view, who may share and where a photo may be used. A photo may be owner-only, private, protected, public, public but owner-share-only or public and shareable. A gallery may have default rights, but a specific photo may override them. Access through a specific chat, post or profile is an attachment/context right. This means the photo may be in the library but visible only through the specific place when that is chosen. If the owner changes the rights of a photo or gallery, the system should apply the new rights in a controlled way and should not allow silent bypass through old attachments. The right to view is not the right to forward. This is a core rule for protecting personal space.
