* chore: remove orphaned helpers after v2 waterfall and flamegraph removal
Drop GetSpansForTrace, cacheForTraceDetail, fluxIntervalForTraceDetail from
clickhouseReader — all were only used by the deleted v2 handlers. Also remove
the orphaned model.Span and model.Event types, and clean up the
cacheForTraceDetail initialization from server.go.
