Subject: [PATCH] fix(pipeline): run meltano install in Dockerfile to generate
 catalogs

Meltano elt requires catalog files (tap.properties.json) to exist.
These are generated by `meltano install` which discovers tap schemas
and installs the target-postgres loader. Without this step, `meltano
elt` fails with "catalog file is missing".
