Brooklyn Nicholson c2cb37532c fix(telegram): add cause-agnostic wedged-recovery watchdog so the reconnect ladder can't freeze silently (#66377)
The Telegram gateway could go silently deaf for hours: the reconnect ladder
stalled mid-way (e.g. "attempt 4/10, reconnecting in 40s" then nothing) while
the process stayed active(running), so Restart=always never fired.

Root class: every recovery path — the ladder's re-entry
(_schedule_polling_recovery), the pending-update probe (_probe_pending_updates),
and PTB's error callback — gates new recovery on _polling_error_task.done(). If
that single task wedges on any hung await, all recovery returns early forever
and nothing retries.

The heartbeat loop is a separate task, so make it an independent, cause-agnostic
watchdog: if the same recovery task stays in-flight past
_POLLING_ERROR_TASK_STUCK_TIMEOUT (300s — well beyond a healthy ladder attempt's
bounded stop+drain+start+backoff), force a retryable-fatal so the background
reconnector rebuilds the adapter instead of relying on the frozen ladder. This
guarantees progress regardless of *where* the stall is (issue direction #1),
tracked locally so no task-assignment site needs to change.

Also salvages @koduri-mahesh-bhushan-chowdary's #66492 (drain-await timeout),
which closes the one concrete wedge vector documented in the incident
(_drain_polling_connections' unbounded shutdown()/initialize() on a wedged
CLOSE-WAIT pool). The watchdog covers the rest of the class.
