mattertimesync: add build + server roles

Build role compiles the tagged source on the build host (npm ci + npm run
bundle) into a versioned mattertimesync-<ver>.tar.gz in build_srv_dir. Server
role installs the single bundled .mjs, creates the mattertimesync service user
and a 0700 storage dir for the Matter fabric keys, templates config.json, and
runs a hardened oneshot sync via a systemd timer. Both roles depend on the
nodejs role for Node >=20.
