yiekheng 57786f9d09 feat(bot,web): window-end gate + paused/resume run lifecycle
fire-reminder.ts now:

* Computes windowEnd via @cmbot/shared/windowEndAt(timezone, endHour,
  now). Per-target loop trips the gate before sending; pending rows
  are LEFT pending (not flipped to skipped) so the run is resumable.
* Accepts an optional runId on the FireReminderPayload. When set,
  the handler ATTACHES to that existing run instead of creating a
  new one and only re-tries pending targets. Resume is allowed even
  when the reminder.status is 'paused' (otherwise we couldn't drag
  it back into delivery).
* Final-status logic adds a 'paused' branch (window closed mid-run
  with at least one row still pending AND something delivered);
  failed when window closed before any send; partial / success
  otherwise.
* Lifecycle: a paused run flips the reminder row to status='paused'
  and skips the recurring re-arm. Resuming or completing later
  flips it back to 'active'.
* SSE event payload gains optional sent/total counts.

reminderFiredToNotification picks up:
* New 'paused' headline + 'X of Y groups delivered. Tap to resume
  or cancel.' body.
* 'partial' body uses sent/total when present.

WebEventMap and the bot's WebEvent union match the new shape.

Tests:
* fire-reminder.test.ts gains a "resume against paused reminder
  acquires mutex" case.
* notifications.test.ts gains 3 paused/partial-sent body cases.
