chore:add Sentry SDK initialization and logging enhancements

This commit updates the Sentry SDK setup to use a cleaner and more explicit approach by checking `SENTRY_DSN` once at the beginning. It also adds an info-level log message when Sentry is disabled and improves logging configuration by explicitly adding Sentry to loggers, ensuring better observability.
