get Tray Position
Determines the position of the system tray icons based on the current operating system.
The method evaluates the operating system in use and retrieves the corresponding tray position.
On Windows, it uses the platform's native library to determine the tray position.
On macOS, it defaults to a specific standard position.
On Linux, the position can be fetched from an application-specific properties file, if available.
For unknown or unsupported operating systems, a default position is returned.
Return
The computed tray position as a TrayPosition enum value.
