feat(plans): report-history + AI-3D limits read from the catalog (S3 finish)

The last two limits that still read hardcoded PlanLimits now come from the
admin-editable catalog, so editing them in the admin panel takes effect:

- ReportPlanGate is now limit-driven (takes int maxDays, not a tier); ReportsController
  resolves MaxReportHistoryDays from catalog.GetLimitsAsync. LimitMessage is generic
  (reflects the actual days). EnsureReportDateAllowed is now async.
- MenuAi3dGenerationService.ResolveLimitAsync reads MaxMenuAi3dPerMonth from the catalog.

Every plan limit + feature gate is now DB-driven and admin-editable. 86 tests pass.
