Pass cql_config to prepare() so that statement preparation can use CQL-specific configuration rather than reaching into db::config directly. Callers that use default_cql_config: - db/view/view.cc: builds a SELECT statement internally to compute view restrictions, not in response to a user query - cql3/statements/create_view_statement.cc: same -- parses the view's WHERE clause as a synthetic SELECT to extract restrictions - tools/schema_loader.cc: offline schema loading tool, no runtime config available - tools/scylla-sstable.cc: offline sstable inspection tool, no runtime config available Signed-off-by: Pavel Emelyanov <xemul@scylladb.com> Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
