Merge main into the Utilities panel, rebuilt on the Vue panel rail

main moved the panels to Vue views and a one-open-panel rail, and removed
the two templates this branch edited. This merge carries the branch onto
that architecture; it adds no behaviour of its own beyond the port.

- The Utilities panel is a RailPanel in LayerPanelsView with its own rail
  item (handyman). LayerPanel renders the Directions rows into its list with
  LayerRows, and falls back to Data Layers without it.
- Draw leaves DisplayPanel for DrawControls, DrawMarkList and DrawSwatches,
  which render what the draw tool publishes to the display store and call
  its actions, as GeoImport does. drawMarks.js words the rows; the DOM-built
  drawMarkList.js is gone. A row's fly-to is an immediate navigation like
  Import's ('drawing' gets its Cockpit refusal), the name field keeps a
  draft through v-field-value, and the colours are one radio group with a
  single tab stop.
- UiSegmented draws an option's icon, named by its label, for the shape
  buttons.
- The catalogs take main's languages with this branch's strings, Arabic
  included, and the tests follow the views to their new homes.
