WJ import loader: resolve notification employee SSOs to names

Notifications imported with only employeesso, leaving employeename null - the
model displays "employeename or employeesso", so recognition/training cards
showed a bare SSO instead of a name. Build an SSO -> "First Last" map from the
employee source and populate employeename (comma-separated SSOs -> joined
names). SSOs not in the directory (former/non-WJF) stay null and fall back to
the SSO, as before.

Verified on the import DB: 261 notifications re-imported, names resolved
(Brandon Saltz, Jon Kolkmann, ...).
