Create migration 007 to raw-SQL CREATE TABLE IF NOT EXISTS the users table as a safety net for fresh databases where Base.metadata.create_all() may fail due to import errors before the table is created. Wrap the create_all call in env.py with try/except so alembic never crashes due to create_all failures — migrations already handle table creation. Co-Authored-By: Paperclip <noreply@paperclip.ing>
