feat(layers): Recent Imagery — open satellite imagery for a selected box (#716)

Select a box on the world and browse the last 30 days of open satellite imagery over it, keyless: NASA GIBS Harmonized Landsat Sentinel-2 (30 m) and the VIIRS daily overview (250 m), with a day strip, IMAGE / VS BASEMAP / A / B modes with a swipe divider, PNG export and share links. The before/after swipe from the Nepal scene moves into shared modules so both use it.
