Add PLSS vector tile layer to overlay selector

[Copilot]

This adds the Utah PLSS vector tile service to the map’s overlay options so users can toggle it alongside parcel-related context layers. The change keeps the existing overlay behavior intact while exposing PLSS directly in the layer selector.

• Overlay configuration

  • Added the PLSS VectorTileServer URL to app config.

• Layer selector

  • Added a new PLSS overlay entry to the map layer menu.
  • Kept the existing Land Ownership overlay and appended PLSS as an additional operational layer.
  • Defined the new PLSS overlay inline in MapContainer per review feedback.

operationalLayers: [
  'Land Ownership',
  {
    label: 'PLSS',
    function: () =>
      new VectorTileLayer({
        url: config.plssVectorTileService,
      }),
  },
],

• UI reference
  • Screenshot for review:

The separate file and unit tests are overkill. Just add the new layer inline. Keep the URL in the config.

Addressed in 1ed38b7. The PLSS layer is now defined inline in MapContainer, the URL stays in config, and the extra helper/test files were removed.
