Enhance GitHub Workflows and Refactor BFF Code

- Added support for push and workflow_dispatch events in pr-checks.yml to improve CI flexibility.
- Implemented concurrency control in workflows to manage job execution more effectively.
- Updated pnpm setup to include caching and specified version for consistency.
- Removed redundant logging code from BFF application to streamline signal handling and improve readability.
- Introduced CSRF_SECRET_KEY validation in environment configuration for production hardening.
- Refactored logo component to use a fallback mechanism for image loading, enhancing user experience.
- Added linting scripts to package.json for improved code quality checks.
