_parse_index_line now extracts the emailAddress segment from the DN
alongside CN, returning a (cn, expiry, email) triple. CertInfo gains an
email field populated by both load functions.
In _main(), RENEW_SELECTED falls back to cert.email when the metadata
store has no entry for the CN — so certs created outside this tool (or
before the metadata store existed) pre-fill the email field correctly.
