Refactor API and Transform Layers for Shared Configuration and Simplified Logic

[ismailtsdln]

API Layer Refactor

GraphSenseClient (Singleton Pattern)

• Introduced a singleton class to manage API configuration and client instances.

• Ensures configuration is loaded only once and shared across all transforms.

• Eliminates redundant client initialization and improves consistency.

Improved Entity Creation

• Completely rewrote the create_entity_with_details function to be more robust and maintainable.

• Handles different query types consistently.

• Replaced dictionary indexing with explicit object attributes for improved type safety and readability.

Configuration Factorization

• Centralized currency-specific constants (e.g., Satoshi / Wei conversion factors) into a standard configuration dictionary.

• Improved consistency and ease of maintenance for currency-related calculations.

Transform Layer Refactor

Centralized Extraction Logic

• Moved common address and currency extraction logic into transforms/utils.py.

• All transforms now rely on extract_address_and_currencies, which uniformly handles:

• Cluster IDs

• Explicit currency filters

• Automatic currency detection

Simplified Transforms

• Significantly simplified ToDetails.py, ToTags.py, and ToCluster.py.

• Removed repetitive boilerplate related to property extraction and error handling.

• Delegated shared logic and error display to utility functions, improving readability and maintainability.
