test(gateway): drop inline GalaxyAlarmAttributeMappingTests (owned upstream by lib 0.2.0)

The package's ZB.MOM.WW.GalaxyRepository namespace shadows the bare
'GalaxyRepository' class reference in this inline test (CS0234). The lib
now owns the identical mapping test, so remove the duplicate (pulls one
file of Task 10's test reconciliation forward to keep Tests compiling).
