fix(client): endpoint port rewrite, Part 13 time-weighted aggregates, clean history-refusal error (#678.5, #677.5, #674.6, #678.6)

- EndpointSelector rewrites host AND port to the user-supplied URL (same scheme only)
- AggregateType/mapper/CLI/UI gain TimeAverage, TimeAverage2, Total, Total2, Interpolative
- HistoryReadCommand turns ServiceResultException into a one-line CommandException
- NodeManagerHistoryReadTests non-historized case sets IsReadModified=false
