[Feature]: Data Migration and Hierarchy Transformation Tool

[asterixix]

Is your feature request related to a problem? Please describe.
With the introduction of hierarchical organization structures, existing flat organization data needs to be migrated to the new hierarchical model. Currently, there's no tool to help administrators convert their existing associations into proper hierarchies, which will lead to difficulties in adoption and data inconsistencies when transitioning to the new model.

Describe the solution you'd like
Implement a data migration and hierarchy transformation tool that includes:

• Wizard interface for mapping existing organizations to hierarchical relationships
• Visualization of "before and after" organization structures
• Validation checks to prevent circular dependencies and orphaned organizations
• Simulated migration with impact analysis before actual execution
• Automated permission adjustment based on new hierarchical relationships
• Data consistency checks throughout the migration process
• Rollback capability in case of migration errors
• Migration history and audit logging
• Incremental migration option for large organizational structures
• Template-based suggestions for common hierarchy patterns

Describe alternatives you've considered

1. Manual data restructuring by administrators
2. Database-level scripts executed by technical staff
3. Starting fresh with new organizations and manually transferring data

Additional context
This migration tool is critical for the successful launch of the Advanced Association Management MVP as it will enable existing users to adopt the new hierarchical features without losing their data or relationships. The tool should be intuitive enough for non-technical administrators to use while ensuring data integrity throughout the transformation process.
