fix(telegram): restore transient retry with throttle-based recipient filtering

The previous commit was modified by the pre-commit hook and lost two
critical pieces: the transient-error retry scheduling and the raised
throttle constant.

This commit restores both:
- TRANSIENT_RETRY_DELAY_MS = 60 s (retry interval on network failure)
- STALE_THROTTLE_MS = 70 s (> retry interval, so a recipient that just
  posted STALE is throttled on the 60 s retry cycle but re-evaluated
  when the missed-threshold timer fires minutes later)
- null branch reschedules at TRANSIENT_RETRY_DELAY_MS instead of
  silently dropping the notification

No retryFor/scheduleInternal — all recipients are re-evaluated on every
invocation; the throttle naturally suppresses recently-succeeded ones.
