fix(spp_dci_openg2p): use canonical registry_type URI in SR-import wizard

The wizard's data_source_id domain filtered on the short alias
'SR', which only exists in the dispatcher's URI-to-alias routing
map — not as a stored field value. spp.dci.data.source.registry_type
is a Selection over URIs from spp_dci.schemas.constants.RegistryType,
so the filter never matched and the Source Registry dropdown rendered
empty.

Switch the domain, the _default_data_source search, and the seeded
data XML to 'ns:org:RegistryType:Social' so the dropdown picks up
the Social Registry source on fresh installs and the operator sees
the configured source pre-filled.
