Subject: [PATCH] test: add unit test for b64_encode helper

Added a unit test `test_b64_encode` for the `b64_encode` function in `src/resolver/registry.rs`.
The test validates standard behaviors like encoding an empty string, common credentials ("user:pass"), and a string requiring padding ("hello world").
