OliverW d6e006f086 Improve task executor heartbeat handling and cleanup (#12390 )

Improve task executor heartbeat handling and cleanup.

### What problem does this PR solve?

- **Reduce lock contention during executor cleanup**: The cleanup lock
is acquired only when removing expired executors, not during regular
heartbeat reporting, reducing potential lock contention.

- **Optimize own heartbeat cleanup**: Each executor removes its own
expired heartbeat using `zremrangebyscore` instead of `zcount` +
`zpopmin`, reducing Redis operations and improving efficiency.

- **Improve cleanup of other executors' heartbeats**: Expired executors
are detected by checking their latest heartbeat, and stale entries are
removed safely.

- **Other improvements**: IP address and PID are captured once at
startup, and unnecessary global declarations are removed.

### Type of change

- [x] Performance Improvement
