Replace the free-text bounding-box field in the Web App OpenSky
settings with a grouped preset picker (World / Continents / Countries)
plus a Custom option that keeps the manual lamin,lomin,lamax,lomax
entry. Saved values that match a preset render as the friendly region
name, including in the locked/inherited display.
Change the API Server default bounding box to Europe to match the new
"Europe" preset.
