feat: configurable component-level logging (#575)

* 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.

* refactor: update logging configuration in environment files

* fix: adding coderabbit suggestions

* fix: ensure correct audit caller

* fix: include reason in audit login failure logs
