Update EFT overdue in 7 days email distribution list

Add in some of our team members to this distribution list so we are aware what EFT accts will lock due to no payment.

Add Patty.stemkens@gov.bc.ca
maybe a dev as well?

No file, test, or entry point is named in the issue. First locate the EFT overdue-in-7-days email distribution list, confirm how recipients are configured, and clarify whether a developer should be added; done means the requested team member receives the email and the recipient list is verified.
