fix(deploy): StartLimit* directives belong in [Unit], not [Service]

Browse source 
systemd 230+ moved StartLimitBurst= and StartLimitIntervalSec= from
[Service] into [Unit] (with the rename from StartLimitInterval=). Putting
them in [Service] makes systemd silently ignore them with a warning to
journalctl: "Unknown key 'StartLimitIntervalSec' in section [Service],
ignoring." — meaning the restart-loop cap I claimed in commit 519567e
wasn't actually applied.
