Subject: [PATCH] Core.yaml: Add device classes for many entities

Most importantly, set atmospheric_pressure on pressure, because it was
failing to graph together with other atmospheric_pressure entities.
Somehow, it ended up as pressure, despite not having a device class
set.

Put aqi's device class in quotes, per the esphome docs.
