Subject: [PATCH] feat(cli): add test-email command to check mail capability

Added a new test-email CLI command that checks if the system has mail utilities
installed (mail, sendmail, msmtp). This command does not send an email but simply
verifies the availability of outbound mail capability on the server. Useful for
verifying mail setup without triggering any actual message.
