feat: Use SQL functions instead of GetSqlInfo for instrumentation discovery

Replace getSqlInfo() with a standard SQL query using GIZMOSQL_INSTRUMENTATION_ENABLED(),
GIZMOSQL_INSTRUMENTATION_CATALOG(), and GIZMOSQL_INSTRUMENTATION_SCHEMA() functions.
This avoids JDBC driver compatibility issues with custom SqlInfo IDs.

+- OAuth discovery, initiation, and polling API routes (`/api/oauth/discover`, `/api/oauth/initiate`, `/api/oauth/poll`)
+- Server info API route (`/api/server-info`)
+- SQL functions for instrumentation metadata discovery (`GIZMOSQL_INSTRUMENTATION_ENABLED()`, `GIZMOSQL_INSTRUMENTATION_CATALOG()`, `GIZMOSQL_INSTRUMENTATION_SCHEMA()`)
