plugin-map: no fitBounds to data — markers land on an adjacent world copy, initial viewport shows an empty map #4941

Observed

Map list view (MapLibre-based plugin-map), driven by objectstack examples/app-showcase at framework SHA 189a732254e6c46af75cfa38462693e67408d2d3 (showcase task object, seeded US-city coordinates):

• The initial camera does not fit the data: markers are rendered on an adjacent world copy (longitude-wrapped), so the first paint shows a map with no visible markers; reaching them takes manual zoom-out + pan.
• Context: the showcase map view declares no custom style, so the plugin falls back to the public MapLibre demo style (demotiles.maplibre.org), whose productionization notice banner shares the screen. Not a defect by itself, but it amplifies the empty-first-paint impression.

Expected

On load, the camera fits the bounds of the queried records' coordinates (normalized longitudes / fitBounds over the marker set), so a view with data never opens on an empty ocean.

Repro

# in objectstack repo
git checkout 189a7322
cd examples/app-showcase && pnpm dev
# open the task object's map view — first paint has no markers in viewport;
# zoom out: markers sit on a neighbouring world copy
