fix: correct require paths and database connection in album processors

- Fix rootPath calculation in all album processors (was going up too many levels)
- Use global \ from connection.php instead of calling openDatabaseConnection()
- Fix cleanup code in save_album.php to use existing \
- Update all processors to use proper config file includes (env.php, session.php, connection.php, functions.php)
- Ensures validateCSRFToken() and other functions are properly available
