[Feature]: Bulk Operations for Cross-Organization Management

[asterixix]

Is your feature request related to a problem? Please describe.
Managing resources, permissions, and settings across multiple organizations in a hierarchy is currently limited to one-by-one operations. This creates significant administrative overhead when performing common actions across multiple child organizations or implementing consistent policies throughout an organizational structure.

Describe the solution you'd like
Implement bulk operation capabilities for cross-organization management including:

• Batch processing for resource sharing across multiple organizations
• Mass role/permission updates that cascade through the hierarchy
• Bulk user assignments to multiple related organizations
• Template-based settings deployment to multiple organizations
• Scheduled bulk operations with preview and confirmation steps
• Bulk import/export of organization configurations
• Transaction safety with rollback capabilities for failed bulk operations
• Audit logging for bulk changes
• Filtering and selection tools for targeting specific organization subsets

Describe alternatives you've considered

1. Individual manual operations for each organization
2. Command-line tools outside the main interface for batch operations
3. Scripting capabilities for advanced users

Additional context
This feature is critical for the Advanced Association Management MVP to make administration of complex hierarchies manageable. Without bulk operations, the overhead of managing multiple organizations would be too high, especially for large federations with many subordinate organizations. The interface should provide clear feedback about the scope and impact of bulk operations before they are executed.
