fix(bigquery): final alignment pass from independent multi-agent validation

- Add missing projectId block output (returned by get_table/create_table/create_dataset but was silently dropped from the block's output schema)
- Switch query/rows/schema subBlocks from long-input to code, matching the JSON/SQL field convention used by every other DB integration (clickhouse, mongodb, postgresql, supabase)
