[truthixify]

This PR implements a comprehensive admin permission management system for the LittleFinger DAO platform.

Changes Made

• New Component: AdminPermissionManagerComponent - Core component for managing administrative permissions
• Interface: IAdminPermissionManager - Public interface defining permission management operations
• Structs: AdminPermission enum and related event structs for permission tracking
• Tests: Complete test suite with mock implementation for component validation

Key Features

• Permission Management: Grant/revoke individual or all permissions to admins
• Owner Privileges: Contract owner has all permissions by default and cannot be revoked
• Bitmask Operations: Efficient permission storage and validation using bitmasks
• Event Emission: Comprehensive event logging for all permission changes
• Authorization Checks: Built-in validation ensuring only authorized users can modify permissions

Technical Details

• Comprehensive documentation following project standards
• Type-safe permission definitions with trait implementations
• Efficient storage using Map<(felt252, ContractAddress), bool> for permission tracking

Testing

• Full test coverage including edge cases and authorization scenarios
• Mock implementation for integration testing
• Event verification for all permission operations

This implementation provides the foundation for fine-grained administrative control within the DAO ecosystem.
