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.
A different board generation from issue #162's DA_DF_A51_20_COMMON, also
carrying the '_DF_' modelNum token and so already routed into the
air_dresser registry -- but reporting two resources #162's board doesn't:
/st/airdressercourse/vs/0 -- the course table id (Table_00), read the
same way washer/dryer read /st/washercourse|dryercourse/vs/0. Wired up
as AIR_DRESSER_COURSE's table_href and added to the global ignore list,
mirroring that existing pair exactly.
/airdresseroption/sanitize/vs/0 -- a genuine on/off setting (not covered
by any existing capability), added as AIR_DRESSER_SANITIZE.
Introducing table_href means the course select's translation_key is now
always the table-lookup callable, so the bare 'air_dresser_cycle' catalog
entry added for #162 (only ever used when no table_href was passed) is
unreachable in every case and is removed -- both boards fall back to the
shared 'cycle' entry until their course tables get named, same as
washer/dryer's own precedent for an unrecognized table.
