Add 16 new device classes for specific sensor types and remote controls, update socket class description

[Copilot]

This PR adds 16 new device classes to provide more granular categorization for sensors and remote controls, making it easier for developers to choose the appropriate device class for their specific use cases.

New Sensor Classes Added

Contact & Motion Sensors:

• sensor_contact - For contact sensors that detect open/close states (door/window sensors)
• sensor_occupancy - For occupancy and presence sensors

Environmental Sensors:

• sensor_temperature - For temperature sensors
• sensor_humidity - For humidity sensors
• sensor_pressure - For atmospheric pressure sensors
• sensor_illuminance - For light/brightness sensors
• sensor_air_quality - For air quality sensors (VOCs, CO2, pollutants)
• sensor_rain - For rain and precipitation sensors

Utility Monitoring Sensors:

• sensor_water_flow - For water flow rate sensors
• sensor_gas_flow - For gas flow rate sensors
• sensor_electricity - For electrical parameter sensors (voltage, current, power)

Safety & Leak Detection Sensors:

• sensor_gas_leak - For gas leak detection
• sensor_water_leak - For water leak detection
• sensor_water_freeze - For freeze protection sensors

New Remote Control Classes

• remote_switch - For remote switches and wall switches that control other devices wirelessly
• remote_portable - For portable remote controls like handheld remotes, keyfobs, and mobile devices

Updated Existing Classes

The existing sensor class description has been updated to clarify that it should be used when a device is composed of multiple sensors (e.g., humidity + temperature), while specific sensor types should use the new dedicated sensor_* classes.

The socket class description has been updated to:

Use this device class for sockets (built-in or plug-in socket switches) or fixed switches, e.g. those connected to a light.

This removes the previous mention of the choose_slave pair template and clarifies the class can be used for fixed switches as well.

Implementation Details

• All new device classes include complete translations for all 13 supported languages
• Device class definitions follow the established pattern with meaningful titles and descriptions
• Generated locale files are excluded from this PR as they are automatically generated
• All existing tests continue to pass
• New device classes are properly loaded and accessible through the existing API

This change provides better semantic categorization while maintaining full backward compatibility.

Fixes #586.

@copilot Please also change the socket class description to:

Use this device class for sockets (built-in or plug-in socket switches) or fixed switches, e.g. those connected to a light.

(drop the choose_slave mention).
