Bump openssl to 0.10.80 to fix CVE-2026-45784 (#3629)

Updates `openssl` 0.10.79 → 0.10.80 (and `openssl-sys` 0.9.115 →
0.9.116) in `Cargo.lock` to address
[GHSA-phqj-4mhp-q6mq](GHSA-phqj-4mhp-q6mq)
/ CVE-2026-45784.

This is a potential out-of-bounds write in
`CipherCtxRef::cipher_update_inplace` for AES-KW-PAD ciphers
(`EVP_aes_{128,192,256}_wrap_pad`). The advisory's first patched version
is 0.10.80.

Resolves Dependabot alert #35. Lockfile-only change; `cargo xtask fmt
--fix` passes.
