shorten entity IDs

[Gifford47]

The current entity IDs are very long, f.e.: switch.picam2ctrl_fullpageos_picamera2_picam2ctrl_fullpageos_awbenable

More convenient ID would be: switch.picam2ctrl_fullpageos_awbenable

Mmh, this is a quite strange entity id for AWBEnable

• It seems your hostname is 'fullpageos' ?
• switch is not used in entity ids but only for HA discovery topics.

The typical ID is picam2ctrl.<HOSTNAME>.PiCamera2 picam2ctrl.<HOSTNAME>.AwbEnable and generated by HA internally derived from the MQTT device's name + state topic id as I see.

I decided to use the <'HOSTNAME'> because unique identifiers for the device and the topic id are required if more than one webcam is available. Only the PiCamera2 part is redundant.

But it is already planned to setup the topic prefix "picam2ctrl" & "" in the config.json file to be more flexible if only one webcam is available.
