For a basic display of UUID (which I think we should stick with for now), you'd
best display the entire UUID because vendor chosen UUIDs may have meaningful
data at any location in the UUID, including the last character. E.g. there could
easily be a vendor who chose to use these:
12341234-1234-efde-1523-785fea000001
12341234-1234-efde-1523-785fea000002
12341234-1234-efde-1523-785fea000003


Later, we could have a smarter display that detects if the UUID is using the
bluetooth base UUID
https://www.bluetooth.com/specifications/assigned-numbers/service-discovery and
if so then simplify it. More so, we can look up all standard UUIDs and replace
them with their name and number, e.g. 'generic_access (0x1800)'.


Keep the uuid field in the info-container.

Done.
