db: parenthesize subquery in CleanInactiveUsers

The "id NOT IN ?" placeholder expands the bun subquery without any
surrounding parentheses, so the generated statement reads "id NOT IN
SELECT ..." which SQLite rejects with a syntax error. As a result
"pw admin gc" always fails while cleaning inactive users. Wrap the
placeholder in parentheses so the subquery is valid.
