fix(plant): drop device_class from snmp sensors — empty first render kills add [#344]

Browse Source 
HA 2026.8 raises ValueError(int('')) at entity ADD when a device_classed
snmp sensor's first render is empty (host down at boot/reload), so the
entity silently vanishes (artroom/garage/subopi3). Units alone keep the
°F/W/A display; automations are numeric_state, dashboards don't filter
on device_class.

# NOTE (2026-09-02, HA 2026.8): NO device_class on snmp platform sensors.
# HA 2026.8 hard-fails entity ADD when a device_classed sensor's first
# render is empty (host down/asleep at boot) — ValueError int('') drops
# the entity until manual reload. unit_of_measurement alone keeps °F/W/A
# display; numeric_state triggers and dashboards do not need device_class.
