Drop /XX/ view-model prefix from samples (#690)

The framework no longer routes two-way data through a dedicated XX/ view-
model node - every binding now lives on the root model. Update the samples
that referenced the /XX/ model path directly:

- app_173 / app_176: template model paths {template>/XX/...} -> {template>/...}
- app_346: custom JS model.setProperty("/XX/FOCUSCOLUMN"/"/XX/FOCUSROW") ->
  root paths
- app_461: comment describing the resolved binding-context paths (the
  end-anchored parser already handles the shorter path unchanged)
