test(ops): add queue view coverage for filters, rank ordering, and template context in test_ops_queue.py

[AAdewunmi]

Summary

Adds focused Ops queue view tests in tests/test_ops_queue.py to validate filter behavior, queue ranking, and template context wiring.

What this PR tests

• Filter passthrough from request query params to queue-building logic:
  • status
  • priority
  • sla
• Queue rank assignment for rendered items (one-based queue_rank).
• Template/context contract for queue rendering:
  • items present and ordered
  • filters context values persisted for selected options
  • expected queue template usage

Why

• Protects key UI behavior introduced in the queue wiring work.
• Prevents regressions where filters stop applying, ranks disappear, or selected filter state is lost.
• Improves patch coverage on the Ops queue surface.

Scope

• Test-only change in tests/test_ops_queue.py.
• No production endpoint or model behavior changes.
