Add ServiceCatalog core (hosting_type, development_type, maturity_level) plus
1:1 per-dimension extension tables (service_third_party, service_first_party,
service_cloud, service_self_hosted) keyed by service_id. Migration creates the
tables and copies existing tpsc_catalog rows into service_catalog as
(cloud_hosted, third_party), reusing the tpsc_catalog id as the service_catalog
id so existing tpsc_entries.catalog_id keep resolving without a column change.
GDPR/data-processing fields move to service_cloud; pricing_model to
service_third_party.
