mxaccesscli: route write through Advise vs AdviseSupervisory by user

WriteCommand now picks the LMXProxyServer advise variant based on
whether credentials were supplied:

  --username given  -> Advise            (operator action; the write
                                          is attributed to the
                                          authenticated Galaxy user
                                          in the alarm/event audit
                                          trail)
  no --username     -> AdviseSupervisory (supervisory action; the
                                          write is attributed to the
                                          hosting client itself, no
                                          Galaxy user claimed)

MxItem grows AdviseSupervisory() alongside Advise() and shares the
same UnAdvise / RemoveItem teardown.

Verified live with the trigger / ack-as-dohertj2 / clear sequence on
TestMachine_001.TestAlarm002. The Set (anonymous, supervisory) and
Clear (anonymous, supervisory) rows pair with the Acknowledged row
(authenticated, Advise) under one Alarm_ID. On this development
galaxy every action still maps to User_Name=DefaultUser regardless
of advise variant — that's a galaxy-security configuration trait,
not a CLI bug. The routing is in place and will differentiate
correctly on a strict galaxy with real user records.

docs/usage.md gains an "Advise variant" section explaining the rule
and the expected User_Name population on strict vs permissive
galaxies.

> ⚠️ Verified behavior on the test galaxy used during development: `AuthenticateUser` returned `userId=1` for both the correct password and intentionally bad credentials (incl. an unknown username). This is consistent with a galaxy configured in `Free Access` mode where security checks are effectively disabled — the CLI's auth path is wired correctly, the galaxy just isn't strict. To exercise real authentication, target a galaxy with `galaxyAuthenticationMode` enabled and attribute-level security classifications above `Free Access`.
### Advise variant — operator vs supervisory
`write` picks how it subscribes to the destination attribute (the briefly-active subscription used for type resolution before the Write call) based on whether you supplied credentials:
| `--username` supplied? | Advise variant used | Audit-trail intent |
| --- | --- | --- |
| Yes | `LMXProxyServer.Advise` | Operator action — attribute the Write to the authenticated Galaxy user. |
| No (anonymous) | `LMXProxyServer.AdviseSupervisory` | Supervisory action — attribute the Write to the hosting client (no Galaxy user claimed). |
This affects how System Platform records the action in the alarm/event subsystem and the Historian's `Events` table. On a strict galaxy with `galaxyAuthenticationMode` and real user records:
- Authenticated + `Advise``User_Name = <galaxy user>`, `User_Account = <galaxy domain>\<user>`.
- Anonymous + `AdviseSupervisory``User_Name` typically NULL or the supervisory client identity.
On a permissive galaxy (the development config used here), every action maps to `DefaultUser` regardless of advise variant — the mechanism is wired correctly but can't be differentiated until galaxy security is configured with real users. See [`Authentication`](#authentication) above.
### Reusing an already-resolved `userId`
`AuthenticateUser` may be expensive (involves SQL Server lookup + Windows cred check). For batch scripts that issue many writes, call `AuthenticateUser` once via a manual call, capture the `userId`, then pass it directly via `--user-id <N>` to subsequent `write` invocations. This skips the per-call auth round-trip.
