feat(browse): pass live driver config to driver-page address pickers (follow-up #2)

AbCip/TwinCAT/FOCAS driver-config pages host the same *AddressPickerBody as the /uns TagModal but
did not pass GetConfigJson, so their universal Browse button would capture against an empty {} (no
device). Thread SerializeCurrentConfig through. DriverType is left to the picker-body default
(canonical registered type) rather than the page's DriverTypeKey const, whose TwinCAT/FOCAS values
("TwinCat"/"Focas") are non-canonical casing that could miss the factory TryCreate lookup.
