refactor: lightbox ID generation and shadow management

Replaces the async SHA-256 based unique ID generation with a synchronous hashCode method in Utility. Refactors LightBox to manage Shadow instances in a local cache instead of querying the DOM, and removes the static find method from Shadow. Also extracts image link wrapping logic into a helper method for clarity.
