The file hosting uses non-deterministic URLs, so replace legacy_ks2_base_url
+ legacy_ks2_years with a single legacy_ks2_urls object mapping year codes
to download URLs. Configure the 4 pre-COVID years in meltano.yml.

Meltano 4.x requires an environment to be specified. Set production as
the default. Also remove the deprecated 'version: 2' field.

The meltanolabs target-postgres variant expects 'database' as the
config key, not 'dbname' (which was the pipelinewise variant's key).

c576bba06a fix(meltano): remove catalog capability and switch elt to run

The `catalog` capability forced Meltano to run --discover and generate
a catalog file (tap.properties.json) before each extraction. This fails
because our Singer SDK taps emit schemas inline and don't need external
catalog files. Removing the capability makes Meltano invoke taps
directly without catalog generation.

Also switch from deprecated `meltano elt` to `meltano run` for
Meltano 4.x compatibility.

Airflow 2.10 requires SQLAlchemy <2.0, but dbt-postgres 1.8+ pulls in
SQLAlchemy 2.x. Airflow 2.11 supports SQLAlchemy 2.

Replaces the hand-rolled integrator with a production-grade ELT pipeline
using Meltano (Singer taps), dbt Core (medallion architecture), and
Apache Airflow (orchestration). Adds Typesense for search and PostGIS
for geospatial queries.

- 6 custom Singer taps (GIAS, EES, Ofsted, Parent View, FBIT, IDACI)
- dbt project: 12 staging, 5 intermediate, 12 mart models
- 3 Airflow DAGs (daily/monthly/annual schedules)
- Typesense sync + batch geocoding scripts
- docker-compose: add Airflow, Typesense; upgrade to PostGIS
- Portainer stack definition matching live deployment topology
