Add time sync support and fix LCD temp/humidity sensor

[pkuijpers]

• Add time sync support for Tuya devices via TuyaSpecificCluster
• Fix LCD temp/humidity sensor for _TZE200_locansqn variant

[dlnraja]

✅ Time Sync Already Implemented in dlnraja Fork

The Universal Tuya Zigbee app (dlnraja fork) already includes comprehensive time sync support in TuyaSpecificCluster.js:

Features:

• MCU sync time command (0x24)
• UTC + local time with timezone offset
• Works with TZE284 LCD clocks and other time-aware devices

Code location:

\lib/clusters/TuyaSpecificCluster.js\ - \ imeSync()\ method

Thanks for the contribution! The LCD sensor fix for _TZE200_locansqn\ may be valuable - I'll review that part.

Hi! Thanks for this PR.

Already in our fork (v5.11.13):

• _TZE200_locansqn -> climate_sensor

Tracked in dlnraja/com.tuya.zigbee.

[dlnraja]

_TZE200_locansqn is in climate_sensor already, and we handle mcuSyncTime in TuyaBoundCluster. Thanks for the PR though — if there's a specific LCD display issue with this variant, happy to look at it with a diagnostic report.
