Refactor: Centralized Configuration Management for Predictify Hybrid Contract

[1nonlypiece]

Overview

This PR introduces a comprehensive configuration management system for the Predictify Hybrid contract, centralizing all constants, configuration structs, and environment-specific settings into a new config.rs module. This improves maintainability, flexibility, and clarity for all contract configuration.

Key Changes

• New config.rs module:

  • Centralizes all contract constants (fees, voting, market, extension, resolution, oracle, storage).
  • Provides configuration structs for each settings group (fees, voting, market, extension, resolution, oracle, network).
  • Implements environment-specific configuration (development, testnet, mainnet).
  • Adds configuration validation and helper utilities.
  • Includes configuration testing utilities and documentation.

• Refactored usage across modules:

  • All constants in fees.rs, voting.rs, extensions.rs, and related modules now reference config.rs.
  • Contract interface exposes configuration management methods:
    • initialize_with_config
    • get_contract_config
    • update_contract_config
    • reset_config_to_defaults
    • get_config_summary
    • fees_enabled
    • get_environment
    • validate_configuration

• Test Coverage:

  • Added comprehensive tests for configuration initialization, update, reset, validation, and environment detection.

• Removed duplication:

  • All configuration values are now defined in one place, eliminating scattered constants.

Benefits

• Clean, organized configuration management
• Centralized and modular configuration
• Environment-specific and flexible settings
• Improved validation and documentation
• Easier maintenance and extensibility
