Group Microsoft/OneDrive no-PTR ranges into one district

OneDrive's IPs (e.g. 13.107.x, 150.171.x) have no PTR and weren't in our
CIDR table, so each fragmented into its own IP-named district — a long
session showed dozens, all with the "OneDrive" process subtitle. Add the
documented Microsoft 365 service ranges so they collapse to one Microsoft
district. Deliberately excludes generic Azure tenant space, which would
mislabel third-party apps hosted on Azure.
