test: update dirsize/md5 probe with path-variant comparison results

Three path formats tested against NAS:
  a) plain string        -> 599 (wrong, task fails silently)
  b) json.dumps([path])  -> works (JSON array is the correct format)
  c) json.dumps(path)    -> 599 (wrong, double-encoded string)

Confirms current implementation (json.dumps(paths)) is correct.
MD5 probe simplified to final confirmed settings (status v1, 0ms).
