Merge branch 'feature/audit-log-m8-cli': Audit Log #23 M8 CLI

M8 — the final milestone — ships the operator CLI surface:
- ManagementService /api/audit/query + /api/audit/export endpoints
  (minimal-API, HTTP Basic + LDAP auth, OperationalAudit / AuditExport
  role gates reusing M7's AuthorizationPolicies role sets).
- scadalink audit command group:
  - audit query: full UI-parity filter set, keyset-cursor paging
    (--all follows nextCursor), JSON (default) / table output,
    AcceptOnlyFromAmong fast-fail validation on channel/kind/status.
  - audit export: streams server CSV / JSONL to --output (parquet → 501
    per v1.x deferral), required-flag enforcement.
  - audit verify-chain: v1 no-op stub (hash-chain deferred to v1.x);
    validates --month, prints the deferral message, exits 0.
- Table output formatter for audit events.
- Pre-existing audit-log config-change command renamed audit-config;
  audit-log retained as a deprecation alias (stderr warning).
- CLI README documents the audit group, the rename, permissions.

Review fix: corrected --channel/--kind/--status help + README to the
real enum names (ApiOutbound/DbOutbound/Notification/ApiInbound, etc.)
and added AcceptOnlyFromAmong so a bad value fails fast instead of
silently returning unfiltered results; removed the dead --instance flag
(AuditLogQueryFilter has no instance column).

Shipped: 10 commits, ~62 net new tests.

=== Audit Log #23 — implementation complete (M1-M8) ===
Full solution: 24 test projects, 2,993 tests, 0 failures, 0 skipped.
dotnet build ScadaLink.slnx clean. infra/* never touched on any of the
8 milestone branches. alog.md changed exactly once (M1 vocabulary
reconciliation, committed before the dependent code merge per the
ordering invariant).

# Audit Log #23 — M8 CLI Implementation Plan
> **For Claude:** subagent-driven-development with bundled cadence. FINAL milestone.
**Goal:** Operator CLI surface — `scadalink audit query | export | verify-chain` — plus the ManagementService HTTP endpoints they call, output formatters, and renaming the pre-existing `audit-log` config-change command to `audit-config` with a deprecation alias.
**M7 realities baked in:**
- `OperationalAudit` + `AuditExport` are role-claim policies (M7 Bundle G). The Management endpoints reuse them.
- `IAuditLogRepository.QueryAsync` (keyset paging) + `GetKpiSnapshotAsync` exist.
- `AuditLogQueryFilter` is single-value per dimension — the CLI's `--channel` etc. flags collapse to single values like the UI chips do (documented limitation).
- `verify-chain` is a v1 no-op stub (hash-chain deferred to v1.x per alog.md locked decisions). Do NOT implement hash chains.
- ManagementService surface: confirm controllers vs minimal API by reading the project (M7 found CentralUI uses minimal API; ManagementService may differ).
**CLI conventions:** System.CommandLine; JSON default + `--format table` opt-in. The CLI connects via the HTTP Management API (per CLAUDE.md). Mirror `src/ScadaLink.CLI/Commands/AuditLogCommands.cs` for the System.CommandLine pattern.
**Bundles:**
- Bundle A — CLI `audit` command group: scaffold + query + export + verify-chain (T1, T2, T3, T4).
- Bundle B — ManagementService /api/audit/{query,export} endpoints (T5).
- Bundle C — Output formatters + audit-config rename + README (T6, T7, T8).
Final cross-bundle review + merge + roadmap closeout.

### `audit-log` — Audit log queries
### `audit` — Centralized Audit Log
#### `audit-log query`
Read access to the central append-only **Audit Log** (#23) — the record of every
script-trust-boundary action: outbound API calls (sync + cached), outbound DB
operations (sync + cached), notifications, and inbound API calls. This is distinct
from the configuration-change audit trail exposed by [`audit-config`](#audit-config--configuration-change-audit-log).
Query the central audit log with optional filters and pagination.
The subcommands map directly onto the `GET /api/audit/query` and
`GET /api/audit/export` management endpoints. Filters and the result columns mirror
the Central UI **Audit** page, so a CLI query and a UI query with the same filters
return the same rows — CLI ↔ UI filter parity is intentional.
**Permissions.** Querying requires the `OperationalAudit` permission (roles `Admin`,
`Audit`, or `AuditReadOnly`). Exporting requires the stricter `AuditExport` permission
(roles `Admin` or `Audit`) — read access does *not* imply export access. A request
without the required role returns exit code `2`.
#### `audit query`
Query audit log events with optional filters and keyset pagination.
```sh
scadalink --url <url> audit-log query [options]
scadalink --url <url> audit query [options]
```
| Option | Required | Default | Description |
|--------|----------|---------|-------------|
| `--since` | no | — | Start time: relative (`1h`, `24h`, `7d`) or ISO-8601 |
| `--until` | no | — | End time: relative (`1h`, `24h`, `7d`) or ISO-8601 |
| `--channel` | no | — | Filter by channel (`ApiOutbound`, `DbOutbound`, `Notification`, `ApiInbound`) |
| `--kind` | no | — | Filter by event kind (`ApiCall`, `ApiCallCached`, `DbWrite`, `DbWriteCached`, `NotifySend`, `NotifyDeliver`, `InboundRequest`, `InboundAuthFailure`, `CachedSubmit`, `CachedResolve`) |
| `--status` | no | — | Filter by status (`Submitted`, `Forwarded`, `Attempted`, `Delivered`, `Failed`, `Parked`, `Discarded`, `Skipped`) |
| `--site` | no | — | Filter by source site ID |
| `--target` | no | — | Filter by target (external system, DB connection, notification list) |
| `--actor` | no | — | Filter by actor |
| `--correlation-id` | no | — | Filter by correlation ID |
| `--errors-only` | no | `false` | Show only failed events (`status=Failed`; overrides `--status`) |
| `--page-size` | no | `100` | Events per page (11000) |
| `--all` | no | `false` | Fetch every page, following the keyset cursor |
| `--format` | no | `json` | Output format: `json` (JSONL, one event per line) or `table` |
With `--format table`, events render as an aligned text table with columns
`OccurredAtUtc`, `Channel`, `Kind`, `Status`, `Target`, `Actor`, `DurationMs`,
`HttpStatus`; long `Target`/`Actor` values are truncated with an ellipsis. With
`--format json` (the default), each page is emitted as JSONL — one JSON object per
line — which streams cleanly under `--all` across many pages.
#### `audit export`
Export audit log events to a file. The export streams from the server, so it is not
bounded by the query page size.
```sh
scadalink --url <url> audit export --since <time> --until <time> --format <fmt> --output <path> [filters]
```
| Option | Required | Default | Description |
|--------|----------|---------|-------------|
| `--since` | yes | — | Start time: relative (`1h`, `24h`, `7d`) or ISO-8601 |
| `--until` | yes | — | End time: relative (`1h`, `24h`, `7d`) or ISO-8601 |
| `--format` | yes | — | Export format: `csv`, `jsonl`, or `parquet` |
| `--output` | yes | — | Destination file path |
| `--channel` | no | — | Filter by channel |
| `--kind` | no | — | Filter by event kind |
| `--status` | no | — | Filter by status |
| `--site` | no | — | Filter by source site ID |
| `--target` | no | — | Filter by target |
| `--actor` | no | — | Filter by actor |
> `--format parquet` is accepted by the CLI but the server returns `501 Not
> Implemented` — Parquet archival is deferred to v1.x (see `Component-AuditLog.md`).
> Use `csv` or `jsonl`.
#### `audit verify-chain`
Verify the audit log hash chain for a given month.
```sh
scadalink --url <url> audit verify-chain --month <YYYY-MM>
```
| Option | Required | Default | Description |
|--------|----------|---------|-------------|
| `--month` | yes | — | Month to verify, `YYYY-MM` (e.g. `2026-05`) |
> **v1 no-op.** Hash-chain tamper-evidence is not enabled in this release. The
> subcommand validates the `--month` argument and prints a notice pointing at the
> v1.x roadmap in `Component-AuditLog.md`; it exits `0` without contacting the server.
> The command exists now so scripts and operator habits do not need to change when
> tamper-evidence ships.
---
### `audit-config` — Configuration-change audit log
Query the configuration-change audit trail (the `IAuditService` record of admin
edits to templates, instances, sites, etc.). This is **separate** from the
centralized [`audit`](#audit--centralized-audit-log) group above.
> **Renamed.** This group was named `audit-log` before #23 M8. The old name still
> works as a deprecated alias — `scadalink audit-log query ...` resolves the full
> subcommand tree unchanged — but prints a deprecation warning to stderr:
> `Warning: 'audit-log' is deprecated and will be removed in a future release. Use 'audit-config' instead.`
> Migrate scripts to `audit-config`; the `audit-log` alias will be removed in a
> future release.
#### `audit-config query`
Query the configuration-change audit log with optional filters and pagination.
```sh
scadalink --url <url> audit-config query [options]
```
