Remove set -e and database dependency from certificate scripts

Improved certificate renewal and sync scripts to be more resilient:
- Removed 'set -e' to prevent silent failures when individual domains error
- Scripts now continue processing remaining domains even if one fails
- Replaced database queries with direct filesystem scanning of /etc/letsencrypt/live/
- Uses 'find' command to discover all domains with Let's Encrypt certificates
- More reliable as it works even if database is out of sync

Benefits:
- No silent failures - errors are logged but don't stop the entire process
- Works independently of database state
- Simpler and more straightforward
- All domains with certificates get processed regardless of database
