fix(messages): skip map-related legacy fallback for mower devices

[Beennnn]

Summary

When a mower (Ecovacs GOAT G1, A1600 RTK, A3000 LiDAR Pro, …) is mowing, its firmware pushes spontaneous onMapTrace MQTT messages. They flow through messages.get_message() which falls back via _LEGACY_USE_GET_COMMAND to GetMapTrace, whose parser does not support the on-wire format used by recent mower firmware (observed: 1.15.13). The parse fails inside _handle_error_or_analyse and emits a WARNING per push.

In one user setup this produced 217 520 Could not parse getMapTrace warnings over 3 days (~70k/day, ~50/min during mowing), bloating the HA homeassistant.log and the recorder DB by ~100 MB.

Mowers do not expose a map= capability in their hardware definitions (see 0jbd6s, 2ap5uq, 2i0fns, 5xu9h3, aadham, xmp9ds, itk04l), so even if the legacy fallback succeeded, the parsed map-trace data would have nowhere to land. The fallback is pure noise on these devices.

Change

Add an optional device_type: DeviceType | None = None argument to get_message and get_legacy_message. When the device is a MOWER, map-related legacy messages are skipped silently before reaching the parser:

_MAP_LEGACY_COMMANDS = frozenset({
    "getCachedMapInfo", "getMapSet", "getMapSubSet",
    "getMapTrace", "getMinorMap", "getMultiMapState",
})

Vacuums (DeviceType.VACUUM) and callers without a specified type (None) fall through unchanged — fully backwards compatible.

Device._handle_message reads device_type defensively via getattr so existing tests mocking Capabilities with spec_set= (which excludes dataclass field names from dir()) continue to work — they fall back to the no-filter path.

Test plan

• test_get_messages (existing 7 cases) — pass unchanged
• test_get_messages_device_type_filter (10 new cases) — verify mowers skip map-related legacy fallbacks while non-map messages and other device types remain unaffected
• Full suite: 707/707 tests pass, no regression
• Real-world: user reports back after deploying a custom HACS build (will follow up in Disable getMapTrace() for Ecovacs Goat Lawn Mower #1376 once HACS release ships this change)
