fix(metrics): correct Redis key pattern in overview aggregation

The overview endpoint was returning zero counts because scanKeys()
couldn't find any matching keys due to incorrect pattern.

Problem:
- Used pattern: queue_metrics:jobs:*:*:*
- Actual keys:   laravel_database_queue_metrics:jobs:redis:default:...
- Laravel's Redis prefix was not included in the pattern

Solution:
- Build full pattern: [redis_prefix][our_prefix]:jobs:*
- Pass full keys to getHash() (no prefix stripping needed)

Tested in sandbox with 40+ FastJob executions - now correctly
aggregates total_jobs_processed and total_jobs_failed.
