When migrateDB() upgraded the transactions table to add the 'waste'
CHECK constraint, the new table was created WITHOUT the 'undone' column.
The migration then tried to build idx_transactions_pid_type_undone, which
references 'undone' → PDOException SQLSTATE[HY000].
Fix:
- Add undone INTEGER DEFAULT 0 to the migration CREATE TABLE
- Replace 'INSERT INTO transactions SELECT * FROM transactions_old'
with explicit column list (transactions_old may predate undone column)
Fixes: #56
