✨ Migrate from testify to nalgeon/be testing library

- Replace all testify/assert and testify/require with be library
- Update go.mod to use be v0.3.0 instead of testify
- Simplify test assertions using be.Equal, be.Err, and be.True
- Refactor append_test, entry_test, meta_test, log_test, and formatter tests
