The superimposed cards grid had its column width hardcoded via a SCSS
variable ($metrics-min-card-width: 335px) and never read the dynamic
cardMinWidth setting from the store.

Regular card grids (CardGridComponent) receive cardMinWidth as an input
and apply it via [style.grid-template-columns], which overrides the
SCSS default. Superimposed cards were missing this entirely.

Changes:
- SuperimposedCardsViewContainer: select getMetricsCardMinWidth from the
  store and pass it as [cardMinWidth] to the presentation component.
- SuperimposedCardsViewComponent: accept cardMinWidth input, compute
  gridTemplateColumn in ngOnChanges (same logic as CardGridComponent),
  and bind it via [style.grid-template-columns] on the grid div.

Fixes #55

When a line chart has disableUpdate=true (card not yet visible via
intersection observer), the container may be resized by persistResize
restoring a saved height, or by a full-width class being applied
asynchronously from the store.  The ResizeDetectorDirective's skip(1)
can batch this resize with the initial ResizeObserver event, causing
the only notification to be swallowed.  The chart then holds stale
dimensions from ngAfterViewInit, so the renderer draws curves at one
scale while the interactive overlay positions tooltip dots at another.

Fix: when disableUpdate transitions from true to false, re-read the
DOM dimensions and resize the chart renderer so both the canvas and
the coordinate mapping match the current layout.
