fix: correct buffer variable name and update thumbnail background color generation

- Renamed 'fileData' to 'fileBuffer' for clarity in the UploadSongDto structure.
- Changed the method for generating the thumbnail background color from 'faker.internet.color()' to 'faker.color.rgb({ format: 'hex' })' for improved color accuracy.
