dtoro 50e899e5ee fix(checks): stop process_check.sh emitting invalid JSON, and mint one kind ...

`systemctl is-active` prints the state AND exits non-zero when a unit is not
active, so `... || echo unknown` appended a second line: STATE became
"inactive\nunknown" and the script emitted a raw newline inside a JSON string.
The scheduler rejected all 14 process checks with "invalid character '\n' in
string literal".

Latent since the script was written — process checks never actually ran,
because checkdefaults wrote an `args` config the ssh-script checker ignored.
Passing args through finally executed them and exposed it.

- head -1 keeps the state, and the fallback only fires on empty output.
- Quotes are stripped from both the unit name and the state; either would
  break the hand-built JSON just as thoroughly.
- signalKind is now the constant "process" rather than "$SERVICE". Emitting
  the service name minted a distinct signal kind per service (kind=paperless,
  kind=qbit, …) — nothing an approval_rule can match, and it makes "how many
  process checks are failing?" unanswerable.
