This commit introduces a new trending works feature to the application.
The feature includes:
- A new `Trending` domain model to store ranked works.
- An `UpdateTrending` method in the `AnalyticsService` that calculates a trending score for each work based on views, likes, and comments.
- A background job that runs hourly to update the trending works.
- A new `trendingWorks` query in the GraphQL API to expose the trending works.
- New tests for the trending feature, and fixes for existing tests.
This commit also includes a refactoring of the analytics repository to use a more generic `IncrementWorkCounter` method, and enhancements to the `WorkStats` and `TranslationStats` models with new metrics like `readingTime`, `complexity`, and `sentiment`.
