Fix viomi map download by triggering a cloud map upload

Viomi vacuums do not keep a map in the cloud. They upload the current map only when sent the set_uploadmap miio command, and the uploaded map is stored as cloud object "1" (not "0"). ViomiCloudVacuum therefore always failed to download a map with "Object Not Found".

ViomiCloudVacuum now overrides get_map_name() to send set_uploadmap through the existing cloud miio relay (get_other_info -> /v2/home/rpc/<device_id>) before returning map name "1". This keeps the viomi platform pure-cloud, with no local connection added. On a failed upload it returns None so the caller raises FailedMapDownloadException and retries.

Also widens get_other_info's parameters annotation to dict | list: legacy miio commands such as set_uploadmap take positional list params.

Verified end-to-end against a live viomi.vacuum.v8.
