feat: add PostgreSQL query and visualization control (#2)

Replace the generic plugin template with a MapLibre GL control that
queries PostgreSQL via a DuckDB-backed API and renders results with
GeoArrow and deck.gl. Connection strings stay server-side, and an
example backend attaches PostgreSQL sources as read-only DuckDB catalogs.
