Use Google's BigQuery JDBC driver instead of the Simba driver - #2547

…imba driver The webapi-bigquery profile now pulls com.google.cloud:google-cloud-bigquery-jdbc (Apache-2.0, shaded 'all' jar), so no manual driver download or local install is needed. Existing Simba-style connection strings (ProjectId, OAuthType, OAuthServiceAcctEmail, OAuthPvtKeyPath) are accepted unchanged.

WebAPI 34cadca0 (OHDSI/WebAPI#2547) swapped the classpath-provided Simba driver for com.google.cloud:google-cloud-bigquery-jdbc, but it declares it in the `webapi-bigquery` profile. A profile is re-evaluated, not baked into the installed pom, so consuming WebAPI as a dependency never carries that driver through however the install was invoked — the wrapper module has to declare it, which is what this does (same coordinates, `all` classifier, runtime scope, transitive deps excluded because the shaded jar carries them). Without a driver on the image's classpath a BigQuery Source cannot connect: DataAccessConfig probes each supported driver with Class.forName and skips the ones that are absent, and a closed-world native image cannot pick one up from disk at runtime the way the servlet deployment could. Registering the driver class for reflection is what makes that Class.forName resolve. The shaded jar ships its own META-INF/native-image metadata for the gRPC/Netty/gax/OpenTelemetry stack it bundles, so native-image picks those hints up on its own; only the driver class needs a hand-written entry. Note this is the JDBC path WebAPI uses for a BigQuery Source. bao's datamart cache is unaffected: BigQuery is a native-scanner dialect there and goes through DuckDB's bigquery extension, not JDBC.
