Subject: [PATCH] feat(slots): thread rescheduledBy param from URL through to
 tRPC input
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Split of #28636 (Part B of 3). Plumbing only — adds a new `rescheduledBy`
search param that flows from the URL through `useScheduleForEvent` →
`useSchedule` → the tRPC `getSchedule` input schema. Nothing consumes
the field yet; it will be read by `_getGuestBusyTimesForReschedule` in
Part C to gate guest busy-time blocking on host-initiated reschedules.

Concretely:
- `apps/web/modules/schedules/hooks/useEvent.ts`: reads
  `searchParams.get("rescheduledBy")` alongside the existing
  `rescheduleUid` read and forwards it to `useSchedule`.
- `apps/web/modules/schedules/hooks/useSchedule.ts`: adds
  `rescheduledBy` to `UseScheduleWithCacheArgs` and passes it through
  to the tRPC query input.
- `packages/trpc/server/routers/viewer/slots/types.ts`: adds
  `rescheduledBy: z.string().nullish()` to `getScheduleSchemaObject`.

Backwards compatible — the field is nullish on both the URL and the
schema, so older clients keep working unchanged.
