[Copilot]

Pull request overview

This PR updates the basemap/overlay system to support TileJSON-based sources (including remote TileJSON URLs) and refactors the basemap schema to separate type-specific fields into dedicated tables.

Changes:

• Added UI support for a new “TileJSON” overlay/basemap entry mode and a read-only TileJSON details view.
• Updated basemap backend routes/models/types to accommodate the schema split (vector/raster/terrain tables) and a new tilejson field.
• Adjusted test fixtures to align with updated nullability for iconset/attribution.
