The goal of this refactoring is to eliminate the global configuration singleton (`config.Cfg`) and replace it with explicit dependency injection of a `Config` struct.
This commit includes the following partial changes:
- The `Config` struct in `internal/platform/config/config.go` has been updated with all necessary fields.
- Several platform packages (`db`, `cache`, `auth`, `http`, `jobs/sync`) have been modified to accept the `*config.Config` struct.
- The API server entry point (`cmd/api/main.go`) has been updated to load and provide the configuration.
- A new worker entry point (`cmd/worker/main.go`) has been created to house the background job runner, as per the architecture defined in `refactor.md`.
NOTE: The build is currently broken as this refactoring is incomplete. This commit is for saving progress as requested.
- Fixes a potential panic in the background job queue by changing `log.Fatalf` to `log.Printf`, allowing for more graceful error handling.
- Implements all `panic("not implemented")` methods in the mock repositories for `Like`, `Work`, and `User`, enabling more robust testing.
- Consolidates duplicated `WorkAnalytics` and `TranslationAnalytics` structs into a central `internal/domain/analytics` package to reduce code duplication and improve maintainability.
- Corrects build errors that arose during testing, including an unused import and an incorrect struct field name in a mock repository.
Replaces a raw `panic` in the `asynq` server startup with a call to `log.Fatalf`.
If the job server fails to start, it is an unrecoverable, fatal error. Using `log.Fatalf` ensures the application exits with a clear error message and a non-zero status code, which is a more conventional and robust way to handle fatal startup errors than panicking.
