fix(apps/amm): make the AMM UI load in Basecamp

Stage Logos.Wallet at the plugin root as pure QML (Basecamp rejects the
  prefer :/qt/qml/... resource), move NavBar into qml/chrome/ so it stops
  colliding in Basecamp's shared import path, and add a QML_IMPORT_PATH
  wrapper so standalone still resolves the root module. Adds amm-ui-lgx /
  amm-module-lgx aliases for addressable Basecamp installs.
