Continues narrowing SamsungEntityDescription accesses to the correct
subclass and asserting Optional write_fn/match_fn/exists_fn fields are
set before calling them, per the pattern established in the previous
commit.
Adds [tool.ruff] and [tool.ty] config to pyproject.toml with a curated
ruff rule set (E, F, W, I, UP, B, C4, SIM, RUF, ASYNC, LOG, G, PIE, RET,
PERF, N), pins ruff/ty in requirements-dev.txt, reformats the whole tree
with `ruff format`, and fixes the pre-existing lint and type-check debt
those tools surfaced so both run clean.
Production-code type fixes include: HA's ConfigFlowResult vs. the
generic FlowResult in config_flow.py, narrowing BoundEntity.desc to its
platform-specific subclass (SelectDesc/NumberDesc/SensorDesc/etc.) via
cast() instead of an unchecked annotation, converting HA device_class
strings to their proper enum types, a resolve_registry callback typed
as `object` instead of `DeviceRegistry | None`, and a couple of other
narrow correctness fixes (CA key type validation, an index-out-of-bounds
false positive from an empty-tuple fallback, a bool/dict argument swap).
Test-file fixes are mechanical: narrowing SamsungEntityDescription to
the correct subclass via isinstance()/cast() before accessing
subclass-only fields, and asserting Optional write_fn/unit_fn fields
are set before calling them.
Since entity.py started routing named descriptors through the catalog
under desc.key, SamsungEntityDescription.name has been read for its
value nowhere -- only twice as a flag, to decide whether an entity was
translated at all. That left 148 English names duplicated between Python
and translations/en.json with nothing keeping them honest: six had
already drifted, invisibly, because editing the Python side changes
nothing a user sees.
So the field is gone, and translation_key defaults to desc.key. A
descriptor now sets translation_key only to share one catalog entry
across descriptors or to point at a differently-named one, and the
catalog is the only place an entity name exists.
Every descriptor resolves to exactly the translation key, icon, entity
category, enabled-default and gating it did before -- with one
deliberate exception: the hood fan, previously the sole descriptor with
no key at all, now resolves to 'fan'. That is inert, because fan.py sets
_attr_name = None so the entity presents as the device itself.
The three helpers that forwarded a name into a descriptor
(laundry.bool_option_switch, washer._bool_option_switch, air_purifier's
sensor table) lose that parameter. test_translations.py now requires a
catalog entry for every descriptor rather than only translated ones.

Issue #27: the flex-zone/cooler-drawer select vanished after a device
stopped including supportedOptions on an update for /mode/vs/0.
ObserveManager.apply() handed reps straight to StateCache.apply_rep,
which fully replaces the cached rep -- so a partial update (missing a
field the select's exists_fn/options_field gate on) silently erased
data a fuller update had previously supplied. apply() now merges
incoming reps onto whatever's already cached instead.
Also give ice-maker entities (and any future pattern-cap instance) a
device-given display name instead of the href-derived "Icemaker
One"/"Icemaker Two": Capability.name_field lets a pattern capability
read and normalize an instance name (e.g. iceMaker.name's "CUBED_ICE")
for use as the entity name prefix, independent of the stable
key/unique_id.
