Add Tuya ZS-300TF / ZS-301 soil fertility sensor quirk

[zichul]

Summary

Adds a quirk for the Excellux ZS-300TF Tuya TS0601 soil fertility sensor (commonly sold as the ZS-301). The device pairs with ZHA but exposes no entities without a quirk, because its datapoints are only mapped by a Zigbee2MQTT converter, not by zha-quirks.

The device reports a corrupted manufacturer ID (_TZE2841000000_hdml1aav), so the quirk matches both the clean (_TZE284_hdml1aav) and corrupted form, following the same pattern already used for the Giex GX04.

Exposed entities

Entity	DP	Conversion
Soil moisture	3	raw (%)
Temperature	5	/10 (°C)
Humidity	101	raw (%)
Illuminance	102	raw (lx)
Electrical conductivity (soil fertility)	112	raw (µS/cm)
Battery	15	raw (%)

Notes

• The datapoint map is sourced from the authoritative Zigbee2MQTT converter for this device (zigbee-herdsman-converters, model ZS-300TF, vendor Excellux), see tuya.ts fingerprint ["_TZE284_hdml1aav", "_TZE2841000000_hdml1aav"].
• Illuminance uses a raw (lambda x: x) converter rather than the tuya_illuminance log10 default, because this device reports actual lux (matching the Z2M tuya.valueConverter.raw converter for DP 102).
• The battery is mapped via the Tuya datapoint (DP 15) for accuracy, consistent with the other TS0601 soil-sensor quirks in this file.

Verification

Tested on Home Assistant Yellow (Core 2026.8.x, ZHA). After enabling the quirk and reconfiguring the device, the data-query spell produced real values on cluster 0xEF00:

• DP 3 = 48 → 48.00 % soil moisture
• DP 5 = 226 → 22.60 °C
• DP 101 = 68 → 68.00 % humidity
• DP 102 = 0 → 0 lx (night)
• DP 15 = 94 → 94 % battery
• DP 112 = 856 → 856 µS/cm

pytest tests/test_tuya_sensor.py tests/test_quirks_v2.py tests/test_quirks_v2_builder.py passes (81 tests), and ruff check / ruff format --check are clean.
