refactor(deployments): one paged read of DeploymentRecords + close its three drifts

Deferred-work register rows 37, 86, 87, 88 — the structural duplication and the
three behavioral divergences it had accumulated, fixed together.

Row 37 (structural). `IDeploymentManagerRepository.QueryDeploymentSummariesAsync`
is DELETED. It and `QueryDeploymentListPageAsync` were two paged reads of the same
insert-only table with different contracts — raw offset vs page number, no total vs
total, no instance join vs joined, instance-id-list scoping vs site-id scoping. The
CLI/HTTP `QueryDeployments` handler now goes through `QueryDeploymentListPageAsync`
with a `DeploymentListFilter`, exactly like the Central UI page. The
`DeploymentRecordSummary` projection went with it (`DeploymentListRow` is the single
row shape); its `MaxPageSize` const moved to `DeploymentListPage`, which also gains
`DefaultPageSize`.

Row 86 (Medium, authorization — the headline). `SiteScopeService.ResolveAsync` was
claims-only, so an Administrator carrying `SiteId` claims saw the whole fleet through
the CLI (`ManagementActor.EnforceSiteScope` has always exempted Administrator) and
only their granted sites on the Deployments page. One user, one dataset, two answers.
Administrator = system-wide is the intended semantic on both sides; the UI was the
defect. The role claim is read explicitly with an OrdinalIgnoreCase comparison rather
than via `IsInRole`, which compares claim VALUES ordinally and only resolves when the
identity carries the matching roleType — the two sides must not disagree on a
differently-cased role name. An Administrator's site claims are not collected at all,
so the invariant "system-wide => empty permitted-id set" holds for every caller.
Designer is NOT exempt: the class doc claimed "any Admin/Design user" is system-wide,
which was true of neither side, so the doc was corrected rather than the bypass
widened.

Row 87 (Low). The scoped branch used to resolve the site grant into an instance-id
list by loading EVERY instance in the system, non-transactionally, on every scoped
query; the grant now rides as `SiteIdScope` and is resolved by the query's own join.
An unparseable permitted-site id is DROPPED, never ignored — dropping can only narrow
a grant, discarding it would widen it to fleet-wide. And `PageSize <= 0` no longer
means UNLIMITED down at the repository (`--page-size 0` materialized the whole
retention window): it means "unspecified" and takes the CLI's own default of 50,
capped at 1000. Bounding without telling would be silent truncation, so the handler
now returns a `DeploymentQueryResult` envelope carrying `totalCount` plus the page
coordinates actually applied — with a CLI table projection (mirroring row 57's
`AuditConfigTableProjection`) that unwraps it and appends a "showing N of M" note.

Row 88 (Low, UX). An unrecognised `--status` fell back to "no filter", so a typo like
`--status Sucess` returned every status — a complete-looking answer to a question the
caller never asked. It is now a `ManagementError` naming the valid values. Parsing
stays case-insensitive; a numeric string is rejected too, since `Enum.TryParse`
accepts "7" and yields an undefined value (guarded with `Enum.IsDefined`). Loud
failure over silent full results, per row 46.

Tests: 7 new `SiteScopeServiceTests` pinning Administrator = system-wide (verified
failing 6/7 against the pre-fix service, the Designer pin passing both ways); the
ManagementActor deployment suite migrated onto the consolidated query with new pins
for the status error, case-insensitive parse, numeric rejection, page-size default/
cap/floor, empty-scope-on-garbage-grant, and "reads no instances at all"; a repository
test for site-scope+status composing over a bounded page; and 6 CLI tests for the new
table projection.

 - **DeployArtifacts**: Deploy system-wide artifacts (shared scripts, external system definitions, DB connections, data connections) to all sites or a specific site. The command's `SiteId` is honored (arch-review C2): a value routes to the single-site deploy path (`ArtifactDeploymentService.DeployToSiteAsync`), while `null` deploys fleet-wide (`DeployToAllSitesAsync`). Site scope is enforced — a site-scoped (non-Administrator) Deployer may only target a site within its `PermittedSiteIds`, and may **not** deploy fleet-wide (`SiteId is null` is rejected with `SiteScopeViolationException` → `ManagementUnauthorized`, since `EnforceSiteScope(null)` is a deliberate no-op); fleet-wide deployment requires a system-wide Deployer or Administrator.

The handler previously ignored `Status`, `Page` and `PageSize` entirely (the CLI had been sending them all along) and loaded the whole insert-only `DeploymentRecords` table; for a site-scoped user it additionally loaded every instance and intersected the two sets in memory. Site scope is now resolved to the set of in-scope instance ids and pushed into the query as an id filter — an **empty** scope stays a real filter (a user permitted no in-scope instances sees nothing), never a no-op. This read path also drives the opportunistic, rate-limited terminal-record retention sweep described in `Component-DeploymentManager.md`.

+  **One paged read, three drifts closed (deferred-work register rows 37, 86–88).** This handler used to own a second repository query, `QueryDeploymentSummariesAsync`, alongside the Central UI page's `QueryDeploymentListPageAsync`. That query is **deleted**; both surfaces now go through `QueryDeploymentListPageAsync` with a `DeploymentListFilter`, and the `DeploymentRecordSummary` projection went with it (`DeploymentListRow` is the single row shape). The duplication had drifted into three behavioral differences, all resolved here:
+  - **Site scope is a SITE-ID filter, resolved by the query's own join to `Instance`** (row 87). It used to be resolved in the handler by loading **every instance in the system** on every scoped query, purely to turn the site grant into an instance-id list — a second whole-table read, non-transactional with the one that mattered. An **empty** scope remains a real filter (a user permitted no sites sees nothing), never a no-op, and a permitted-site id that is not an integer is **dropped rather than ignored** — dropping can only narrow the grant, whereas discarding the grant would widen it to fleet-wide.
+  - **`PageSize` is bounded** (row 87). A non-positive value used to mean *unlimited* all the way down to the repository, so `--page-size 0` materialized the entire retention window into one response. It now means "unspecified" and takes `DeploymentListPage.DefaultPageSize` (50, the CLI's own default); every value is capped at `DeploymentListPage.MaxPageSize` (1000). `totalCount` travels with the bounded page precisely so a truncated page is distinguishable from a complete one.
+  - **An unrecognised `Status` is an ERROR, not "no filter"** (row 88). `--status Sucess` used to fall back to unfiltered and return every status — a plausible, complete-looking answer to a question the caller never asked. It now returns `ManagementError` naming the valid values (`Pending, InProgress, Success, Failed`). Parsing stays case-insensitive; a numeric string is rejected too (`Enum.TryParse` accepts `"7"` and yields an undefined value, so the parse is guarded by `Enum.IsDefined`). Same loud-failure principle as register row 46.
+
+  **Administrator is system-wide** on this path, as on every other site-scoped handler (`EnforceSiteScope`). The Central UI's `SiteScopeService` was claims-only and disagreed — an Administrator carrying `SiteId` claims saw the fleet here and only their sites on the Deployments page. The UI was corrected to match (register row 86); see `Component-CentralUI.md`.
