v1.7.9

Changed

• Deterministic key ownership using Ecowitt's documented sensor priority order: When multiple outdoor sensors share the same common_list keys (e.g. 0x02 temperature, 0x07 humidity, 0x03 dewpoint) and report equal signal strength, the integration now resolves ownership using Ecowitt's documented priority order — WN32/WH26 > WS90/WH90 > WS80/WH80 > WS69/WH69. A WN32 outdoor T/H sensor paired alongside a WH90/WS90 weather station will reliably own the shared temp/humidity/dewpoint keys rather than sharing them based on iteration order. A higher-priority sensor with signal=0 does not block an active lower-priority sensor (signal strength still beats priority). For sensors with equal priority, the previous poll's stable tie-break (issue #197) continues to apply. (issue #203)
