Implement environment variable configuration

[coderabbitai]

Overview

Currently, some configuration values like debug mode are hardcoded. This issue proposes implementing environment variable configuration to make the application more configurable.

Proposed Changes

• Create AppConfiguration struct to manage application-wide configuration
• Read configuration from environment variables with sensible defaults
• Make configuration available throughout the application via Vapor's storage
• Add logging of configuration on startup

Environment Variables

• APP_DEBUG: Enable debug mode (true/false)
• APP_ENV: Application environment (development/staging/production)
• STATIC_PATH: Path for static assets
• DECIMAL_COUNT: Number of decimal places for numerical values
