ADR-0021 Phase 2: migrate example dashboards/reports to dataset dual-form + reconciliation harness

Migrate inline analytics (report/dashboard widgets) in app-todo, app-crm and
app-showcase to the semantic `dataset` form (dual-form, side-by-side with the
legacy inline query), and add a read-only reconciliation harness that asserts
both forms return identical numbers — the hard gate before deleting old form.

Harness (scripts/analytics-reconcile/): boots each app's real kernel and runs
legacy engine.aggregate() vs dataset queryDataset(), diffing numbers group by
group; exits non-zero on mismatch. 52 surfaces reconcile green, 0 mismatch.

Two real runtime bugs the gate caught, both fixed in ObjectQLStrategy (+regression tests):
- same-field filter-operator overwrite dropped a bound of a $gte/$lte range
- timeDimensions were ignored, so date dimensions never bucketed — now lowered
  to a structured {field, dateGranularity} groupBy that engine.aggregate buckets

Also:
- record-list reports (app-todo overdue_tasks, showcase task_list) -> ListViews
- joined report: added block-level dataset dual-form to JoinedReportBlockSchema
  and bound the analytics block (showcase task_overview/open_block)
- fixed example bugs surfaced by reconciliation (created_date->created_at,
  invalid date macros, crm sales_by_stage flat-list -> real grouped sum)

Spec: 6666 tests pass. service-analytics: 89 tests pass.
