feat(node): systemd service panel on the Node page, and a clean CLI restart

Add a status panel at the top of the Node page — always visible, even
before an MNP connection exists — showing the meshbay-node systemd
unit's own state (via `systemctl --user show`, main process only) with
Start/Stop/Restart controls. This is the piece the rest of the page
cannot provide: it has to work while the daemon is stopped or crash-
looping, which the MNP-based sections require the daemon to already
answer.

While touching node lifecycle: `reload` and `restart-daemon` in the
CLI shelled out to pgrep + SIGTERM/SIGHUP and respawned the process by
hand, logging to a hardcoded /tmp path. That pattern already SIGHUPed
a developer's own running node by accident once (see the old
test_cli_dispatch.py comment). Both now delegate to
`systemctl --user reload|restart meshbay-node`, which the unit already
supports correctly (ExecReload=, Restart=on-failure).
