source-monday: refactor GraphQL code into modular architecture with performance and memory improvements

• Restructure monolithic graphql.py (1109 lines) into specialized modules:
  - graphql/activity_logs.py for activity log operations
  - graphql/boards.py for board management
  - graphql/items/ package with items.py and item_cache.py
  - graphql/query_executor.py for centralized query execution with IncrementalJsonProcessor
  - graphql/constants.py for shared constants
• Implement IncrementalJsonProcessor for memory-efficient streaming of large GraphQL responses
• Add item cache system for efficient items backfill operations and reduced API calls
• Enhance API client with improved error handling, complexity management, and debugging capabilities
• Improve code quality, API compliance, and maintainability through modular design
• Update models and resources to support modular architecture
• Add utility functions for common operations
• Update test snapshots to reflect architectural changes

This refactoring addresses data discrepancy (missing data) issues and maintainability concerns
while significantly improving performance and memory efficiency for data synchronization operations.
