fix(queue): correct status deduplication + tier:low soft-fail

CRITICAL SORT-ORDER FIX:
get_combined_status: The /statuses endpoint returns newest-first (desc by
id), but /status's embedded statuses[] returns oldest-first (asc by id).
Previous code did: combined.statuses = all_statuses (newest-first), which
overwrote newer entries with stale ones. Fix: process combined_statuses with
reversed(sorted()) first (newest-first), then fill gaps from all_statuses.

TIER:LOW SOFT-FAIL:
Add _is_tier_low_pending_ok() helper and pr_labels parameter to
required_contexts_green(). Per sop-checklist-config.yaml tier_failure_mode,
tier:low uses soft-fail: sop-checklist posts state=pending (not success)
when manager/ceo items are informational only. The queue now accepts pending
for sop-checklist contexts on tier:low PRs.
