Solves #773. Normally you let Nginx handle the login URL creation but with this "hack"
we can set an arbitary header with where Tinyauth wants the user to go to. Later the
Nginx error page can get this header and redirect accordingly.
* Refactor logging to use centralized logger utility
- Removed direct usage of zerolog in multiple files and replaced it with a centralized logging utility in the `utils` package.
- Introduced `Loggers` struct to manage different loggers (Audit, HTTP, App) with configurable levels and outputs.
- Updated all relevant files to utilize the new logging structure, ensuring consistent logging practices across the application.
- Enhanced error handling and logging messages for better traceability and debugging.
* refactor: update logging implementation to use new logger structure
* Refactor logging to use tlog package
- Replaced instances of utils logging with tlog in various controllers, services, and middleware.
- Introduced audit logging for login success, login failure, and logout events.
- Created tlog package with structured logging capabilities using zerolog.
- Added tests for the new tlog logger functionality.
