docs(offline): mark UR-052 offline-listing feature and its tests Done

The DR-079/DR-080 root-cause fixes for issue #10 landed in 8f4f651; the
requirements doc still listed UR-052 (and DR-078/079/080, UT-068/069/070,
IT-016/017) as Broken/Partial/Pending. Flip them to Done and regenerate the
traceability matrix. Existing backend tests already cover the IT-016/017
end-to-end scenarios (annotated with their IDs in the code commits).
