PROFILEPHOTO: profilePhotoUrl computed field on GerbilDto

Browse Source 
GET /gerbils/{id}: loads first photo by sortOrder (2 queries, no N+1).
GET /gerbils list: batch-loads first photos for the page in one IN query.
profilePhotoUrl = /photos/files/{fileName} or null. No migration.
3 new tests: no-photo=null, sortOrder priority, list batch.
