feat(env): enhance webhook configuration and SSL support

- Added new environment variables for SSL configuration, including `SSL_CONF_PRIVKEY` and `SSL_CONF_FULLCHAIN`, to support secure connections.
- Introduced additional webhook configuration options in the `.env.example` file, such as `WEBHOOK_REQUEST_TIMEOUT_MS`, `WEBHOOK_RETRY_MAX_ATTEMPTS`, and related retry settings to improve webhook resilience and error handling.
- Updated the `bootstrap` function in `main.ts` to handle SSL certificate loading failures gracefully, falling back to HTTP if necessary.
- Enhanced error handling and logging in the `BusinessStartupService` to ensure better traceability and robustness when processing messages.

This commit focuses on improving the security and reliability of webhook interactions while ensuring that the application can handle SSL configurations effectively.
