Refactor error handling in SQL snippets loading

- Simplify error handling in SqlSnippets.vue and Subscribers.vue by removing console error logs.
- Implement silent failure for loading subscriber counts and SQL snippets, ensuring the application remains functional without displaying error messages.
- Set default values for sqlSnippets to an empty array on failure to enhance user experience.
