Add CompanyName and Department to the results CSV

Add-PersonaRunResult now optionally accepts the normalized UserRecord and
pulls CompanyName/Department from it for the results.csv row, via
TryGetValue rather than the Properties dictionary indexer so a record built
without those keys doesn't throw. Kept off the PersonaDecisionResult/audit
contract on purpose - this is CSV-only, not a widening of what gets logged.
