Zoltan Papp 174dc24867 [management] Add SSO session extend flow (management) (#6197)
* add SSO session extend flow (management)

Adds the management-server half of the SSO session-extension feature:

- New ExtendAuthSession gRPC RPC that refreshes a peer's session expiry
  using a fresh JWT, validated through the same pipeline as Login but
  without tearing down the tunnel or redoing the NetworkMap sync.
- Per-peer SessionExpiresAt timestamp on every LoginResponse and
  SyncResponse so connected clients learn the deadline on the existing
  long-lived stream, and admin-side changes (toggling expiration,
  changing the expiration window) reach every peer within seconds.
- SessionExpiresAt(...) helper on Peer that derives the absolute UTC
  deadline from LastLogin + the account-level PeerLoginExpiration
  setting, returning zero when the peer is not SSO-tracked or expiration
  is disabled.

The matching client-side consumer of these fields lands separately.

* encode SessionExpiresAt as 3-state on the wire

Previously the `sessionExpiresAt` field on LoginResponse, SyncResponse
and ExtendAuthSessionResponse was 2-state: a valid timestamp meant
"new deadline", and nil meant "clear". That conflated two distinct
meanings — "no info in this snapshot" vs "expiry is explicitly off /
peer is not SSO-tracked" — so a Sync push that legitimately couldn't
compute the deadline (settings lookup failed) would silently clear the
client's anchor and lose the warning window.

Three states now, encoded on the same field number (no .proto schema
churn — only comments and the server-side encoder change):

  - nil pointer (field absent) → "no info"; client preserves anchor
  - &Timestamp{} (seconds=0, nanos=0) → explicit "disabled / not SSO"
    sentinel; client clears
  - valid timestamp → new absolute UTC deadline

A new encodeSessionExpiresAt helper centralises the zero/non-zero
encoding and is shared by the Sync, Login and ExtendAuthSession
builders. The Sync builder still emits nil when settings are missing.
Login and ExtendAuthSession always carry an authoritative value.

The matching client-side decoder lands on feature/session-extend.

* add UserExtendedPeerSession activity event

ExtendAuthSession previously reused UserLoggedInPeer for its audit
record, which conflated two distinct user actions: a full interactive
SSO login (tunnel re-established, network map resync) versus an
in-place deadline refresh (tunnel untouched). Auditors reading the log
couldn't tell which one happened, and downstream dashboards/alerts on
"login" volume were polluted by routine extends.

Adds a dedicated UserExtendedPeerSession Activity (code 125,
"user.peer.session.extend") and switches ExtendPeerSession over to it.
The peer-extend audit trail is now distinguishable from interactive
logins.

* make ExtendAuthSession JWT-retry backoff cancellable

Skip the retry log and 200ms wait on the final attempt, and replace the
uncancellable time.Sleep with a select on time.After/ctx.Done so an
upstream cancellation aborts the wait instead of running it to
completion.
