Add $year variable support to file path templates

Introduces the $year variable for album, single, and playlist path templates, allowing users to include the release year in file organization. Updates the backend to extract and provide the year, adjusts the web UI to document the new variable, and updates validation logic to recognize $year as valid in templates.
