Chris Lu a736ba1c21 filer: keep metadata-subscription send gauge fresh on idle heartbeat (#9966) ...

* filer: keep metadata-subscription send gauge fresh on idle heartbeat

last_send_timestamp_of_subscribe only advanced when a real matching
metadata event was streamed to a subscriber. On a quiet path an idle but
perfectly healthy subscriber therefore looked increasingly stale, and the
dashboard panel rendered a large, misleading 'lag'.

An idle heartbeat is a send too, so advance the gauge when one is emitted.
Subscribers that opt into idle heartbeats (filer.sync) now report true
freshness; the rest still show time since the last real event.

Rename the dashboard panel 'Metadata Subscription Lag' ->
'Time Since Last Subscription Send' and clarify its description to match.

* filer: guard nil option when advancing heartbeat gauge

maybeSendIdleHeartbeat is unit-tested with a bare &FilerServer{} (nil
option), so dereferencing fs.option.Host for the sourceFiler label
panicked. Guard it: production always has option set; the test now gets
an empty sourceFiler label instead of a nil-pointer panic.
