refactor(ui): text styles from QueryaTextStyles, shadcn TextExtension hidden (#1468)

* refactor(ui): text styles from our own QueryaTextStyles, shadcn TextExtension hidden

xSmall / small / base / large / medium / semiBold / bold / muted /
foreground are a kit extension over DefaultTextStyle with the sizes the
app already used. The widgets.dart barrel and every direct shadcn import
hide shadcn's TextExtension, so call sites are unchanged.

Refs #1465

* fix(ui): hide TextExtension on prefixed shadcn imports, add ellipsis()

An extension from a prefixed import still applies implicitly, so the 27
files importing shadcn as shadcn saw both extensions and every chained
modifier was ambiguous. They now hide it too. QueryaTextStyles also gets
ellipsis() (one line, cut), which one call site used.

* style: child last in QueryaTextStyles calls (sort_child_properties_last)
