Oliver Kieselbach d44dbe7ec0 feat(backend): delegated single-tenant access to /api/global/* reads (MSP switcher) [Phase 2a]
Lets a delegated ("MSP") admin read its managed tenants through the cross-tenant
/api/global/* endpoints — but ONLY on the single-tenant ?tenantId=X path, bounded
by the middleware to a tenant in its allowed set. This is what makes the tenant
SWITCHER work end-to-end (drill into a managed tenant, see its normal dashboard).

The dangerous no-tenantId AGGREGATE path (fan-out over ALL tenants) stays
GA/Reader-only and is untouched here; bounded fleet aggregation is a separate step.

- Middleware: GlobalReadOrAdmin added to the delegated read tier. The existing
  `isScopedRoute && crossTenant` guard means a delegated grant still fires ONLY on
  a tenant-scoped route for an in-scope target — so a delegated caller reaches a
  global endpoint only via its single-tenant path, never the aggregate path.
- Catalog: the 27 GlobalReadOrAdmin routes whose handlers strictly restrict to the
  named ?tenantId= (verified by an exhaustive per-endpoint audit) recataloged
  None -> QueryParam. QueryParam/RouteParam on a GlobalReadOrAdmin route now
  formally means "handler restricts to the named tenant => delegated-reachable";
  aggregate-only routes (presence, platform metrics, distress-reports, config/all,
  …) stay None and remain unreachable by delegated callers. Documented inline.
- Tests: delegated single-tenant global read allowed in-scope / denied out-of-scope
  / denied on the no-tenantId aggregate path; an aggregate-only route stays blocked
  even with an in-scope ?tenantId=; Global Reader aggregate path regression; and a
  catalog-contract theory pinning the SAFE(QueryParam) vs AGGREGATE-ONLY(None) split.
  Updated GlobalAppsRoutes completeness assertion to QueryParam. Full suite green (2461).
