fix(web): drop the client heartbeat column the API can never fill (#6086)

The clients page advertised a connection time in three places -- the table's
`Heartbeat` column, the CSV export's `Connected At` column and the connection detail
dialog -- all bound to `ClientConnectionVO.connectedAt`, a field no provider ever
assigns. `RocketMQClientProvider.toConnectionVO(ProducerInfo, ...)` (`:337`) and
`toConnectionVO(Connection, ...)` (`:469`) build the VO from `ProducerInfo` /
`Connection` payloads that carry no timestamp, and the proxy branch passes none
either, so every cell rendered `-`. That reads as "this client never sent a
heartbeat" rather than "this build does not collect it".

Drop the three surfaces instead of inventing a timestamp the brokers do not report --
the same resolution #5600 took for the fabricated NameServer `Connections` column.
The regression test asserts that the column header, the dialog row and the CSV column
are all gone, and the existing CSV/dialog expectations are trimmed accordingly.
