feat(zigbee): Allow setting mode after Zigbee has started

[P-R-O-C-H-Y]

Description of Change

This pull request updates the setMode method in ZigbeeWindowCovering to improve how the window covering mode attribute is set, handling both cases when Zigbee is started and when it is not.

Improvements to attribute setting logic:

• Updated setMode in ZigbeeWindowCovering.cpp to use esp_zb_zcl_set_attribute_val with proper locking when Zigbee is started, and to fall back to updating the attribute directly when Zigbee is not started, including enhanced error handling and logging in both cases.

Test Scenarios

Please describe on what Hardware and Software combinations you have tested this Pull Request and how.

(eg. I have tested my Pull Request on Arduino-esp32 core v2.0.2 with ESP32 and ESP32-S2 Board with this scenario)
