Subject: [PATCH] fix(settings): enforce trafficDiff max of 100 in UI (#4769)

The trafficDiff InputNumber and form schema lacked an upper bound, so values above 100 were accepted in the UI but rejected by the backend (gte=0,lte=100), failing the entire settings save with a misleading 'request body failed validation' error. Add max=100 to the input and .max(100) to the schema.
