Introduced a new `CacheController` to manage cached data for receiver signatures using distributed caching. Added endpoints to save, retrieve, and delete cached signatures. Created a `SignatureCacheRequest` model for caching payloads and a `CacheOptions` class to configure cache settings, including optional expiration. Updated `Program.cs` to bind `CacheOptions` to the `Cache` section in `appsettings.json`. Added a new `Cache` section in `appsettings.json` with a `SignatureCacheExpiration` property, defaulting to `null` (no expiration).
