Description

Guests couldn't list, restore or download versions of resources shared with them.

• Listing and restoring: both used resource.id. For incoming shares, that is the share jail mount point id. Mount point ids only resolve for accepted shares, and guest shares are never accepted, so the backend returned a 404. Both now use resource.fileId (the actual resource id). For resources loaded via WebDAV, id and fileId are the same, so nothing changes there. This also fixes versions on unsynced shares of regular users.
• Downloading: version downloads always signed the url client-side, which requires a username that guests don't have. getFileUrl gets a new signUrl option. Guests skip signing, since their session cookie authenticates the request, the same way archive downloads already work for guests.

How to test

• Start OpenCloud with: GRAPH_AVAILABLE_ROLES: b1e2218d-eef8-4d4c-b82d-0f1a1b48f3b5,a8d5fe5e-96e3-418d-825b-534dbdf22b99,fb6c3e19-e378-47e5-b277-9732f9de6e21,58c63c02-1d89-4572-916a-870abc5a1b7d,2d00ce52-1fc2-4dbc-8b95-a73b73395f5a,1c996275-f1c9-4e71-abdf-a42f6495e960,312c0871-5ef7-4b3a-85b6-0e4074c64049,aa97fe03-7980-45ac-9e50-b325749fd7e6,63e64e19-8d43-42ec-a738-2b6af2610efa,3d00ce52-1fc2-4dbc-8b95-a73b73395f5a
• Create a file with multiple versions
• Share that file with a guest user, using the editor role that includes listing versions
• Check the shared file as the guest user: listing, downloading and restoring should be possible now
