Setting to control member access while Direct Debit payments are retried

Currently, members paying by Direct Debit regain gym access every time a failed payment goes back into processing, whether it’s an automatic retry or one triggered manually by staff. This means a member whose payments keep failing (e.g. due to insufficient funds) can keep visiting for weeks without ever making a successful payment.

Proposed solution:
Add a club-level setting that lets the club choose how access works during Direct Debit processing:

• Current behaviour (default): members keep access while any payment attempt is processing.

• First attempt only: members keep access during the first processing attempt only. If that payment fails, the membership stays overdue during later retries until a payment succeeds.
