-- Migration 012: Sync existing databases to canonical schema
-- Run this on any existing Hackerspace deployment to align with the canonical schema.sql
-- Safe to run multiple times (idempotent).
--
-- Changes:
--   • Rename space_members.full_name → display_name (to match app code everywhere)
--   • Drop redundant tasks.type text column (canonical column is task_type enum)
--   • Add missing columns to all tables that the app code expects
--   • Create missing unique constraints for upserts
--   • Update handle_space_signup trigger to match canonical version
