Fix search: add username param, fix scope path, add sortBy property mapping

- buildSearchRequest now accepts username parameter for correct scope
- Fix double-slash in scope path when path='/'
- Map sortBy names to correct XML namespaces (size→oc:size, etc.)
- Sort property mapping for: name, size, lastModified, created, favorite
