• call deleteApiKeyCache when you edit or delete an api key

Pull Request Overview

This PR implements a cache invalidation system for API key authentication to ensure consistency when projects, users, providers, or API keys are modified. The changes introduce a project state-based cache invalidation mechanism that uses random UUIDs to track project state changes and verify cache validity.

Key changes:

• Replaced simple API key caching with a project state-based invalidation system
• Added new exported functions (setProjectState, deleteApiKeyCache, setApiKeyCache) for cache management
• Modified apiKeyAuth to accept an ExecutionContext parameter for async cache operations

The magic number 30 should be extracted to a named constant (e.g., CACHE_TTL_DAYS) to clarify that this represents 30 days in seconds. This improves readability and maintainability: const CACHE_TTL_DAYS = 30; const CACHE_TTL = 86400 * CACHE_TTL_DAYS

Suggested change

	const CACHE_TTL = 86400 * 30
	const CACHE_TTL_DAYS = 30
	const CACHE_TTL = 86400 * CACHE_TTL_DAYS
