Reduce default job lock expiration from 24h to 2h (#17)

The job scheduler uses expireLockTime to detect and recover from
stale locks caused by server crashes during job execution.

Previous behavior: Default of 1440 minutes (24 hours) meant jobs
could be blocked for an entire day if a server crashed mid-execution.

New behavior: Default reduced to 120 minutes (2 hours), which:
- Allows recovery from stale locks much faster
- Still provides enough time for most long-running jobs
- Jobs that need more time can set expireLockTime explicitly

Updated ServiceJob entity documentation to reflect new default.
