When sessionwatch.Watcher.Update rejects a deadline (pre-epoch, too far
in the future, or past the clock-skew tolerance) it silently zeroes the
status recorder, leaving the UI with no "expires in" row and no
indication of why. Publish a SystemEvent_ERROR on the AUTHENTICATION
channel so the rejection appears in the UI event feed and the user
knows re-login may be required.
Also add Debugf log lines in armTimerLocked so that warning and
final-warning timer fire-times are visible in logs without having to
add instrumentation after the fact.

The session deadline lived in two sinks kept in sync by hand:
ApplySessionDeadline wrote both the (engine-scoped) sessionwatch.Watcher
and the (server-scoped) peer.Status recorder. The clear paths only
touched the watcher, so the recorder — which is what the Status RPC /
SubscribeStatus snapshot the UI reads from — kept reporting a deadline
that had gone stale, surfacing as a frozen "expires in …" countdown.
Two cases were leaking:
- Profile switch / Down: the watcher is recreated per engine but the
recorder outlives it, so a switch to a profile whose server sends no
deadline left the previous profile's value in place.
- In-place expiry: the watcher arms warning timers at T-WarningLead and
T-FinalWarningLead but nothing at the deadline itself, so once the
moment passed the recorder kept the now-past value indefinitely.
Make the watcher the single writer of the recorder deadline (Update /
clearLocked / Close all route through SetSessionExpiresAt) so teardown
clears it, and guard GetSessionExpiresAt to report a past deadline as
none so in-place expiry stops painting a stale countdown.
Adds an end-to-end SSO session-extension feature: the management server
publishes per-peer session deadlines on every Login/Sync, a new
ExtendAuthSession RPC refreshes the deadline using a fresh JWT without
tearing down the tunnel, and the daemon tracks the deadline locally so
the UI can fire a T-10min warning toast with an interactive "Extend now"
action.
