fix(apidemo): wrappedRowCount via Paragraph.lineCount (currentTextMeasurer removed)

The B6.3 cleanup deleted com.compose.sdl.text.currentTextMeasurer, but apidemo's
Compat.native.kt still used it for wrappedRowCount. Rebuild it on the standard
Paragraph factory (skiko lineCount) — same physical-pixel space (density 1,
fontSize=inFontPx.sp, wrap at inMaxWidthPx). Fixes the v0.3.0 'Build demo +
apidemo release binaries' step, which failed on all targets after the library
publish step had already succeeded.
