fix: OpsPipeline dashboard — use time-filtered doc stages, add time labels

Document Stages now shows time-filtered counts from /health endpoint
(consistent with Parsing/Extraction/Trends sections) with all-time
totals shown as a subtle subtitle from the SSE stream. Added "(last Xh)"
labels to all sections so the time window context is always visible.
