feat(logs): coalesce repeated identical lines into one row (×N badge)

A line identical to the last persisted row (level+source+message+path)
within a 5-min refreshing window updates that row — context._repeat counts
the fold, _firstAt keeps the first occurrence, createdAt tracks the latest
so the storm stays at the top of the newest-first viewer. A continuous
storm stays ONE row however long it rages, so it can't evict unrelated
history via the 50k row cap or grind the appliance disk. LogsViewer badges
coalesced rows ×N (tooltip: count + first occurrence, sq/en). In-memory
last-row cache only; a pruned-under-us row falls through to a fresh insert.
