* Fix startup hook to fire after metadata and schema tables are populated
Previously, the startup() plugin hook fired before internal database
tables were populated from metadata.yaml and before catalog schema
tables were filled. This meant plugins couldn't read or modify metadata
during startup. Now invoke_startup() calls refresh_schemas() before
firing startup hooks, ensuring metadata and catalog tables are available.

Updated test_tracer to reflect that internal DB creation SQL now runs
during startup rather than during the first traced request.
* Move check_databases before invoke_startup in CLI serve
Since invoke_startup now calls _refresh_schemas() which queries each
database, the spatialite connection check must run first to provide
the friendly error message instead of a raw OperationalError.
