fix(ci): disable reqwest default features to eliminate OpenSSL on musl builds

Requiring default-features=false on reqwest prevents native-tls/openssl-sys
from being pulled in as transitive dependencies, which broke static linking
on Alpine musl target. Also reverts invalid openssl-static package from CI.

- Cargo.toml: add default-features = false to reqwest dependency
- ci.yml: revert non-existent openssl-static package
