Filter out archived jobs and inactive customers from job lists

Added customer active status filtering to prevent jobs from deleted
(inactive) customers from appearing in the UI alongside existing
archived job filtering.

Changes:
- Daily Jobs: Filter jobs where customer is NULL or active=True
- Run Checks: Filter jobs where customer is NULL or active=True
- Jobs list: Filter jobs where customer is NULL or active=True

This prevents showing jobs with "-" status from archived jobs or
deleted customers on Daily Jobs and Run Checks pages.
