Add Sentry integration and centralize config loading

- Integrate Sentry.AspNetCore for error monitoring in non-development environments, loading DSN and options from configuration.
- Move configuration building from Startup.cs to Program.cs for earlier access, supporting Sentry setup.
- Update Startup to use pre-built configuration.
- Enhance GitHub Actions release workflow to set versioning properties during publish.
- Centralize and streamline configuration loading for consistency.
