[Feature] Add Audio to the database

[obulat]

Part of #19

Problem Description

This is the general issue for adding Audio to the database in the Catalog.
The columns of the new audio DB table were identified in the API Providers sheet. There should also be a JSON column for meta_data that stores arbitrary, unique and extra data (such as lyrics for some providers).
In addition to the new database table, we also need to add the loading pipeline and the popularity calculations for audio.

Solution Description

• Add audio db table and Update loader task to save the audio data to the DB
• Update popularity calculations in the materialized view to include audio
