Added background check renewal instructions to reminder emails

Churches can now include custom instructions in background check expiration emails to help members understand how to properly renew and submit their checks.

Two new Safe Church settings are available:

• Criminal record check instructions
• Working With Children check instructions (shown for Australian churches)

These details appear at the bottom of the monthly expiration reminder emails, following the standard renewal notice, allowing churches to share local requirements, next steps, contact information, or other helpful guidance with their members.
