Hassfest rejects a filtered device target outright ("Services do not
support device filters on target, use a device selector instead"), and an
unfiltered one would offer every device in the installation. Both services
now take device_id as a required field with a device selector scoped to
this integration -- the shape fully_kiosk, guardian and unifi already use.
No schema change needed: cv.TARGET_SERVICE_FIELDS already accepts
device_id, so the options-flow panel's target= call keeps working.
Also trims the comments added with the review fixes back to the one or two
sentences CONTRIBUTING asks for.
