CARDKITA MUSIC UPLOAD FIX

1. This build includes a .user.ini requesting:
   upload_max_filesize = 25M
   post_max_size = 32M

2. Some cPanel servers ignore project .user.ini settings. If the error still says
   the server limit is 2M/8M, open:
   cPanel > MultiPHP INI Editor > select cardkita.asp3k.com
   and set:
   upload_max_filesize = 25M
   post_max_size = 32M
   memory_limit = 256M
   max_execution_time = 180

3. Ensure these directories exist and are writable:
   uploads/music
   uploads/covers
   uploads/gallery
   Recommended permission: 755. If the host requires it, use 775 only for uploads.

4. Supported music formats:
   MP3, M4A, WAV
   Application limit: 20MB per song.

5. The system now displays the exact PHP upload problem instead of the generic
   'Upload gagal untuk music_file'.
