Subject: [PATCH] Fix default sensor variables causing JS template errors

The default values for motion_sensor, temp_sensor, and humid_sensor were set to the literal strings "variables.motion_sensor", "variables.temp_sensor", and "variables.humid_sensor" respectively.

When a user doesn't provide these sensor variables (e.g. setting show_temp: false without a temp_sensor), the JavaScript template checks like `if (!variables.motion_sensor)` evaluate as truthy because they contain non-empty strings. This then causes the template to attempt `states["variables.motion_sensor"]` which throws:

ButtonCardJSTemplateError: Cannot read properties of undefined (reading 'state')

Changed the defaults to empty strings so the falsy checks work correctly when sensors aren't provided.
