refactor(server): move logger setup to eager entrypoint 
Relocates the global logger configuration from the root middleware (`routes/_middleware.dart`) to the new eager-loading entrypoint (`bin/main.dart`).
This is an architectural improvement that ensures the logger is configured exactly once when the application process starts, rather than within a middleware that could be re-instantiated. It makes the startup sequence more robust and simplifies the root middleware's responsibilities.
