Complete speed dial launcher helper layer; fix tile clip and arrow-nav

Wire the search-first launcher's pure helpers to their node-vm spec:
resultCountText, selectedActionId, actionLabel (accessible row/tile labels
with plugin-key disambiguation), and tileCode (collision-escalating
title/pkg/ordinal monogram). Plus three fixes surfaced by the test + review:

- visibleFavourites drops non-runnable favourites - a dead fav tile
  otherwise renders and run()s to a silent no-op on click.
- .fav-tile mirrors the list tile's inline-flex centering + 12px so a
  multi-char monogram (e.g. "EA1") no longer clips the bare button.
- Arrow Left/Right stop swallowing the search caret in the list zone;
  they only navigate when inside the favourites bar.
