cmd: rename mpc-cli → mpc (pairs with mpcd daemon)

Matches the sshd/ssh, httpd/http unix pattern. Single Docker image
now ships both binaries: ENTRYPOINT is mpcd (the daemon); override
with 'mpc <subcommand>' for CLI ops (peers, identity, recover, etc).

Also aligns with lux/kms (single binary with subcommands) — operators
get the same shape across all Base-family daemons.
