feat(charts): ObjectChart honors the spec ChartConfig author shape (#2880) (#2883)

ChartConfigSchema is the chart protocol, but the renderer only ever read a
Recharts-flavoured internal shape — chartType, xAxisKey, series[].dataKey.
Everything an author wrote in the SPEC shape reached the renderer and was
silently dropped, which is what ADR-0078 forbids.

S1 — normalizeChartSchema translates the author shape into the internal
pipeline contract in ONE place rather than scattering `??` fallbacks through the
render tree: type→chartType, xAxis:{field}→xAxisKey, series:[{name}]→[{dataKey}],
the report surface's bare-string axes, and yAxis:[{field}] alone as the plotted
series. Internal props win, so DashboardRenderer/ObjectView/the dataset path are
byte-for-byte unaffected.

The `type` collision: on any surface that flattens chart config into a props
bag, `type` is already the SDUI envelope's component discriminator — an author
writing type="bar" replaced object-chart and the block stopped resolving. The
react-page wrapper now keeps both: the discriminator wins the `type` slot and
the author's value is preserved beside it as specType.

S2 — ChartAxis.format drives the tick formatter (Intl.NumberFormat, no new
dependency), min/max pin the domain, logarithmic swaps the scale, title labels
the axis, showGridLines is honored. A second yAxis entry (or position:'right')
turns on the secondary axis that series[].yAxis binds to, beating the
family-derived guess in combo charts. showLegend is honored and title/subtitle
render above the plot.

S3 — series[].stack passes through as Recharts' stackId; annotations render as
ReferenceLine/ReferenceArea honoring axis/value/endValue/color/style/label;
interaction.tooltips:false suppresses the hover card, interaction.brush:true
adds the range selector, showDataLabels prints values on the marks.
interaction.zoom has no Recharts primitive behind it and stays unimplemented
rather than faked.

+feat(charts): ObjectChart honors the spec `ChartConfig` author shape (objectui#2880 / framework#3729)
+
+`ChartConfigSchema` is the chart protocol, but the renderer only ever read a
+Recharts-flavoured internal shape — `chartType`, `xAxisKey`, `series[].dataKey`.
+Everything an author wrote in the SPEC shape reached the renderer and was
+silently dropped, which is exactly what ADR-0078 forbids. framework#3725
+documented the gap by trimming the published contract down to the props that
+actually worked; this closes it the other way round.
+
+**S1 — one normalization boundary.** `normalizeChartSchema` translates the
+author shape into the internal pipeline contract in a single place, rather than
+scattering `??` fallbacks through the render tree (framework PD #12: one
+translation is a contract mapping, N fallbacks are a second dialect):
+
+- `type` → `chartType`, `xAxis: { field }` → `xAxisKey`, `series: [{ name }]` →
+  `series: [{ dataKey }]`
+- the report surface's bare-string `xAxis`/`yAxis` resolve too
+- `yAxis: [{ field }]` alone plots, with no `series` declared
+- **internal props win**, so `DashboardRenderer`, `ObjectView` and the dataset
+  path are byte-for-byte unaffected — there is no migration
+
+**The `type` collision.** `ChartConfig.type` is the chart family, but on any
+surface that flattens chart config into a props bag `type` is already the SDUI
+envelope's component discriminator. Spreading props last let an author's
+`type="bar"` replace `object-chart` so the block stopped resolving; stamping the
+discriminator last ate the author's value instead. The react-page wrapper now
+keeps both: the discriminator wins the `type` slot and the author's value is
+preserved beside it as `specType`, which the normalizer reads back.
+
+**S2 — axis presentation.** `ChartAxis.format` drives the tick formatter (via
+`Intl.NumberFormat`, no new dependency), `min`/`max` pin the domain,
+`logarithmic` swaps the scale, `title` labels the axis, and `showGridLines` is
+honored. A second `yAxis` entry (or `position: 'right'`) turns on the secondary
+axis that `series[].yAxis` binds to — in combo charts an explicit binding now
+beats the family-derived bar→left/line→right guess. `showLegend` is honored,
+and `title`/`subtitle` render above the plot instead of only titling the
+drill-down drawer.
+
+**S3 — `series[].stack`, `annotations`, `interaction`.** Stacking passes the
+author's group name through as Recharts' `stackId`. Annotations render as
+`ReferenceLine` (`type: 'line'`) / `ReferenceArea` (`type: 'region'`) with the
+declared axis, colour, style and label. `interaction.tooltips: false` suppresses
+the hover card and `interaction.brush: true` adds the range selector;
+`showDataLabels` prints values on the marks. `interaction.zoom` has no Recharts
+primitive behind it and is deliberately still unimplemented rather than faked.
