Add Samsung air purifier support (ARTIK051_TVTL-class, issue #56)

Adds a by_type registry for the AX60R5080WD/SE air purifier family, verified
against two independent diagnostics dumps (issue #56 and its comment). Binds
power, alarms, energy, diagnosis (reusing dishwasher.DIAGNOSIS), the dust/
fine-dust/super-fine-dust/odor/clean-level sensors off /sensors/vs/0, filter
progress, a device-active diagnostic, and a display-light switch parsed out
of /mode/vs/0's packed options list.

Fan speed/direction (/airflow/0, /airflow/vs/0) and two other /mode/vs/0
tokens (Comode_*, Blooming_*) are exposed as read-only diagnostics rather
than full controls -- neither dump has a supported-values list to confirm
their write contracts, so they're left for a follow-up once that's
clarified in the issue thread.

Hoists range_hood's items[]-sensor-value helper into common.py
(sensor_item_value) since air_purifier now reads the same /sensors/vs/0
shape.

"""Capabilities for the Samsung ARTIK051_TVTL-class air purifier family
(model AX60R5080WD/SE, issue #56 -- verified against two independent
diagnostics dumps of the same internal model).
Power, kids-lock, remote-control, alarms, and the energy meter are the shared
common.py capabilities (this family exposes the standard /power/0+/power/vs/0
pair and /alarms/vs/0, /energy/consumption/vs/0). /diagnosis/vs/0 reuses
dishwasher.DIAGNOSIS -- identical field/write contract
(x.com.samsung.da.diagnosisStart, 'Ready' on both dumps).
Two things are deliberately left as raw, unwritable diagnostic sensors rather
than modeled as real controls, per the "don't guess" rule:
/airflow/0, /airflow/vs/0 -- OCF-standard + vendor pair for fan speed/
direction, both zeroed/'Off' on every dump seen (device was off in both).
No supportedSpeed/supportedModes list is present anywhere in either dump
to confirm the valid range, so a write-capable fan/select isn't safe to
build yet -- see the issue #56 request for a running-state dump.
/mode/vs/0's x.com.samsung.da.options array packs multiple independent
flags into one list (same shape as fridge.FLEX_ZONE's `modes` field, but
keyed `options` here and, unlike FLEX_ZONE, with no `supportedOptions`
list to check membership against). Of the tokens seen:
Light_On / Light_Off -- read as a plain on/off flag; MODE_LIGHT
below models it as a real switch, RMW-
replacing just that one list entry.
Comode_Off -- never seen non-'Off' on these dumps;
likely the fan operating mode the issue
describes (Auto/Sleep/1/2/3), but
unconfirmed -- exposed read-only.
Blooming_0 / Blooming_6 -- meaning unconfirmed; exposed read-only.
OptionCode_60282 -- opaque, unchanged across both dumps;
not modeled (same treatment as
range_hood's OptionCode_* token on the
same href).
