ui: plainer wording across labels and command descriptions

Replace internal jargon and uncommon words in user-facing strings (better for
non-native English readers): drop "TransformRegistry-driven" / "drives
transforms" from the connect/set-connector-type subtitles; "transform lookup"
→ "tells connect how to wire its pins"; "populate pin specs" → "fills in each
pin's role and direction"; "clear the visualization area" → "clear the console
output"; "materialised" → "added"; refresh the verify description. Regenerated
commands.md.
