Add PostGIS to the image - #5

Conversation
Install postgresql-${PG_MAJOR}-postgis-3 (and its scripts package) from the
PGDG apt repo in the base image, alongside pgvector. PostGIS needs no
preloading, so CMD is unchanged.
The smoke test now creates the PostGIS extensions, checks that PROJ and GEOS
load, and verifies a GiST index is used for an ST_DWithin query. The README
documents the extensions and the postgis_extensions_upgrade() step after
version changes.

Summary
postgresql-${PG_MAJOR}-postgis-3and-scriptsfrom the PGDG apt repo already configured in the base image. Because the package name usesPG_MAJOR, it follows a Postgres major upgrade without an edit.CMD/shared_preload_librariesstays as it is.postgis,postgis_topologyandpostgis_raster, runsST_Transform(PROJ) andST_Buffer(GEOS), and checks that anST_DWithinquery uses a GiST index.postgis_extensions_upgrade()step after a PostGIS version change.Needed for Dawarich, which requires PostGIS.
Testing
I built the image locally and ran the workflow's smoke test against it, and it passed. It ships PostGIS 3.7.0 with GEOS 3.15, PROJ 9.9 and GDAL 3.13. The image is now 698 MB.
