feat(realtime): add token state and the presence tracker to the engine (#1460)

* feat(realtime): add token state and the presence tracker to the engine

TokenState keeps (token, generation, exp): stale provider results and nil
are discarded, a refresh is scheduled 60 s before exp, and access_token
pushes are throttled to one per 10 s per channel with the newest pending.
PresenceTracker ports phoenix.js sync: state replaces, diffs merge by key
and phx_ref, early diffs wait for the first state, every meta is kept, and
the tracked payload is re-sent after each rejoin through a coalescing
window that stays under the server's 5 calls per 30 s.

* test(realtime): use a whole-second exp in the token expiry test

Linux's JSONSerialization does not round-trip a fractional Double exactly, which failed the
expiry comparison on CI.

* test(realtime): make makeJWT output deterministic

JSONSerialization does not fix dictionary key order, so two calls with the
same claims could produce different tokens and fail the equality check.

* fix(realtime): pace token refreshes and retry a failed one

A token already inside the refresh leeway made the scheduler call the
provider again with no delay, in a loop. A refresh that returned nil or
the old token scheduled nothing, so the old token stayed until exp.
Every provider call now schedules the next one, at least
accessTokenRetryInterval later.

Also wraps the makeJWT line that failed the format check.

* fix(realtime): keep raw presence messages for inbound listeners

presence_state and presence_diff now reach listeners as .message, as
before, and the tracker's .presenceChanged follows each one.
