Subject: [PATCH] Add database connection helper and live now-playing page

- includes/db.php: getDB() returns a shared PDO connection to MariaDB
- config/db_credentials.example.php: credentials template; the real
  db_credentials.php is gitignored and deployed separately via SFTP
- live.php: page for active broadcasts, with the player on the left
  and a placeholder Recently Played table on the right
