This PR removes the CONF_USERNAME constant (and its associated pylint suppression) from the Tuya integration constants module, likely to avoid duplicating a shared Home Assistant constant.

Changes:

• Removed CONF_USERNAME from homeassistant/components/tuya/const.py
• Removed the home-assistant-duplicate-const pylint suppression previously used for CONF_USERNAME
