useTileUrl returns a new string once carto_api_key reaches the settings
store, which happens after the first render. That string was a dependency
of the effect that *builds* the Leaflet map, so the key arriving tore the
map down and built a new one.
Two things break in that window: Leaflet finishes a queued redraw against
the canvas renderer whose map has gone ("Cannot read properties of
undefined (reading 'save')"), and the country layer never comes back —
its effect only re-runs when its own data changes, so the rebuilt map
shows tiles and nothing else.
The template belongs to the tile layer, not to the map. Hold the layers
in a ref, read the template through a ref inside the build effect, and
setUrl them from an effect of their own. Same fix in JourneyMap, where
cartoKey and mapTileUrl sat in the dep arrays of the effects that draw
every marker and track.
Fixes #2097
