[al-lac]

🤖 This is an automated pull request to update esphome to version 2026.1.4. This PR must be reviewed and tested before merging.

Auto-generated update considerations:

• Web server local assets updated twice (versions 20260122-204614 and 20260127-190637), which may require clearing browser cache if web interface issues occur after upgrade
• Entity ID format migration support added to web server SSE, existing entity references may need verification after upgrade
• HTTP request component fixes for chunked transfer encoding and timeout handling could change behavior of existing HTTP automations
• WiFi component fixes for ESP8266 may alter connection behavior or timing for devices using that platform
• Multiple component-specific bug fixes (mhz19, ld2450, cse7766, ultrasonic) that could change sensor readings or behavior if using those components
