Members Who Qualify for Loyalty Points
Problem
A gym chain logs every membership renewal a member makes. Table `renewals` has `(member_id, renewed_at, fee_cents)` and the pair `(member_id, renewed_at)` is unique.
A member qualifies for loyalty points if they made at least one renewal during the inclusive window from '2023-09-01' to '2023-09-30' that cost at least 5000 cents.
Report a single column `qualifying_members`: the number of distinct members who qualify.
