8e2505b59c [management] Add metrics for peer status updates and ephemeral cleanup (#6196)
* [management] Add metrics for peer status updates and ephemeral cleanup

The session-fenced MarkPeerConnected / MarkPeerDisconnected path and
the ephemeral peer cleanup loop both run silently today: when fencing
rejects a stale stream, when a cleanup tick deletes peers, or when a
batch delete fails, we have no operational signal beyond log lines.

Add OpenTelemetry counters and a histogram so the same SLO-style
dashboards that already exist for the network-map controller can cover
peer connect/disconnect and ephemeral cleanup too.

All new attributes are bounded enums: operation in {connect,disconnect}
and outcome in {applied,stale,error,peer_not_found}. No account, peer,
or user ID is ever written as a metric label — total cardinality is
fixed at compile time (8 counter series, 2 histogram series, 4 unlabeled
ephemeral series).

Metric methods are nil-receiver safe so test composition that doesn't
wire telemetry (the bulk of the existing tests) works unchanged. The
ephemeral manager exposes a SetMetrics setter rather than taking the
collector through its constructor, keeping the constructor signature
stable across all test call sites.

* [management] Add OpenTelemetry metrics for ephemeral peer cleanup

Introduce counters for tracking ephemeral peer cleanup, including peers pending deletion, cleanup runs, successful deletions, and failed batches. Metrics are nil-receiver safe to ensure compatibility with test setups without telemetry.

97bc1eebde [management] Fence peer status updates with a session token (#6193)
* [management] Fence peer status updates with a session token

The connect/disconnect path used a best-effort LastSeen-after-streamStart
comparison to decide whether a status update should land. Under contention
— a re-sync arriving while the previous stream's disconnect was still in
flight, or two management replicas seeing the same peer at once — the
check was a read-then-decide-then-write window: any UPDATE in between
caused the wrong row to be written. The Go-side time.Now() that fed the
comparison also drifted under lock contention, since it was captured
seconds before the write actually committed.

Replace it with an integer-nanosecond fencing token stored alongside the
status. Every gRPC sync stream uses its open time (UnixNano) as its token.
Connects only land when the incoming token is strictly greater than the
stored one; disconnects only land when the incoming token equals the
stored one (i.e. we're the stream that owns the current session). Both
are single optimistic-locked UPDATEs — no read-then-write, no transaction
wrapper.

LastSeen is now written by the database itself (CURRENT_TIMESTAMP). The
caller never supplies it, so the value always reflects the real moment
of the UPDATE rather than the moment the caller queued the work — which
was already off by minutes under heavy lock contention.

Side effects (geo lookup, peer-login-expiration scheduling, network-map
fan-out) are explicitly documented as running after the fence UPDATE
commits, never inside it. Geo also skips the update when realIP equals
the stored ConnectionIP, dropping a redundant SavePeerLocation call on
same-IP reconnects.

Tests cover the three semantic cases (matched disconnect lands, stale
disconnect dropped, stale connect dropped) plus a 16-goroutine race test
that asserts the highest token always wins.

* [management] Add SessionStartedAt to peer status updates

Stored `SessionStartedAt` for fencing token propagation across goroutines and updated database queries/functions to handle the new field. Removed outdated geolocation handling logic and adjusted tests for concurrency safety.

* Rename `peer_status_required_approval` to `peer_status_requires_approval` in SQL store fields

d3f3e08035 Avoid context cancellation in cancelPeerRoutines (#6175)
When closing go routines and handling peer disconnect, we should avoid canceling the flow due to parent gRPC context cancellation.

This change triggers disconnection handling with a context that is not bound to the parent gRPC cancellation.
