feat(core): add functions to retrieve online players by job name or type with optional on-duty check

Adds two utility functions to retrieve online players by either job name or job type, with optional filtering for on-duty status. While the logic is a bit nested, this approach avoids unnecessary function splitting and keeps related behavior in a single place. Although I'm not entirely satisfied with the nesting, this structure felt like a reasonable trade-off between readability and reusability.

This method could also serve as a foundation for deprecating older job-check functions, should the maintainer choose to consolidate similar logic in the future.
