fix(node): stop stale expiry sync from undoing client extensions (#6228) (#6231)
* fix(node): stop stale expiry sync from undoing client extensions (#6228)

After an expired client is extended on the master, a lagging node could
overwrite client_traffics with an older absolute expiry and latch
enable=false. Reject older absolute expiries on merge, ignore
expiry-stale disables when the master is not over quota, lift stale
lifecycle fields out of adopted settings, stamp reconcile fingerprints
from the pre-lift node blob, and mark the node dirty so the next tick
re-pushes.

* fix(node): lockstep client_traffics expiry/enable SQL with review fixes (#6228)

Make expiry merge keep any master absolute (node only activates when master
is unset/duration). Include this tick's up/down deltas in the enable
stale-disable quota check so a crossing-tick disable is not dropped.

* fix(node): add settings absolute helper for renew/lift guards (#6228)

Expose settingsClientAbsoluteExpiry so traffic merge can tell a real
node auto-renew (settings+stats later) from lagging ClientStats after a
master shorten. Trim lift godoc to the invariant.

* fix(node): authority-aware lifecycle merge for multi-node sync (#6228)

While config_dirty, accumulate traffic only — do not adopt node
expiry/enable/total/reset (and preserve dipped baselines so a false
renew cannot fire after clear). On clean ticks, master absolute expiry
wins; node auto-renew still goes through nodeClientRenewed when settings
also show the later deadline. Defer settings lifecycle lift until after
traffic deltas land, align SyncInbound via applyMasterClientLifecycle,
and avoid re-MarkNodeDirty when already dirty.

* fix(node): clear config_dirty only after the post-reconcile traffic merge (#6228)

After a successful ReconcileNode, keep the node dirty through the same
tick's SetRemoteTraffic so lagging ClientStats cannot clobber the
just-pushed master lifecycle, then ClearNodeDirty.

* test(node): cover dirty-gate, master-absolute, and renew false-positives (#6228)

Add regressions for extend/shorten while dirty, clean-sibling shorten,
settings vs lagging disable, renew recovery after dirty, renew with
matching settings, and shorten+Reset lagging stats not treated as renew.

* fix(node): address the review findings on the lifecycle merge (#6228)

The automated review on #6231 flagged a blocking regression and six smaller
issues. All of them are fixed here.

Blocking: making the master's absolute expiry always win left nodeClientRenewed
as the only channel for a node-side auto-renew, and that required a counter dip.
A client that used no traffic in the period never dips, so its renewal was
dropped, the master kept the expired deadline and disableInvalidClients removed
it with no way back (master-side autoRenewClients skips node inbounds). The node
bumps reset_count on every renewal, so that counter is now an independent
renewal signal and is persisted with the renewal so it keeps converging.

The deferred ClearNodeDirty made every reconcile-success tick merge in dirty
mode, which suppressed inbound adoption, new client_traffics rows, the orphan
sweeps and the whole SyncInbound record loop -- and left the node dirty forever
whenever SetRemoteTraffic errored. The clear goes back to where it was; a
separate justPushed flag now freezes only the client lifecycle merge for the
tick whose push just landed.

staleNodeDisable only recognised a lagging disable by an older expiry, so a
quota top-up (raise totalGB, leave the expiry alone) was re-latched to disabled
by the next lagging snapshot -- the #6228 symptom on a second axis. The
reviewer's suggestion of dropping the expiry precondition outright fails
TestNodeQuotaDisable_SameExpiryStillLatches, because the master's own counters
legitimately sit below a node's after a seeded-at-zero adoption. nodeDisableIsStale
instead compares the limits the node judged the client against with the master's
own: matching limits mean a genuine verdict that still latches (#4917), differing
limits mean the node has not seen the master's change yet. It also now measures
the master deadline against wall-clock now, so an expired master row no longer
looks "extended" merely because the node's copy is older still.

Also: the settings lift now writes enable in both directions, so a blob fetched
before a master disable cannot carry enable=true back into central settings and
on to the node; the renewal guard parses the inbound settings once per inbound
instead of once per renewing client; the adoption loop only writes settings when
they actually changed; and two comments that described mechanisms the code does
not use were corrected.

The test deadlines are now relative to the run: the merge compares against now,
so fixed timestamps would have rotted into the wrong side of it.
