Add support for running queue workers and admin interface across multiple database connections (e.g., primary and secondary databases). Features: - Configure connections via Queue.connections array in config - Connection switcher dropdown in admin navigation - --connection option for queue run and queue job commands - Whitelist validation for security - Backwards compatible - only activates with 2+ connections Configuration example: $config['Queue']['connections'] = ['default', 'acme']; The first connection in the array is used as the default. Workers must be run separately for each connection to process its jobs.
