Marc Billow daf7e3787f Add ruff (lint + format) and ty (type checking) to the project
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.

"""Tests for the /temperatures/vs/0 fallback helper in climate.py (PR #36).
`_temps_vs_item` is a pure module-level function (plain dict in, plain dict
out) with no coordinator/entity dependency, so -- like select.py's `_display`
in test_select_display.py -- it's testable directly even though the
LocalThingsClimate entity itself needs a coordinator/hass fixture to
exercise. This covers the actual fallback-selection logic that the
registry-level "no unbound hrefs" tests in test_airconditioner_capabilities.py
don't reach: TP1X-class firmware has no OCF-standard
/temperature/current+desired pair, so current_temperature/target_temperature
would silently be None without this fallback.
