refactor: move handleNotificationWhenNoSlots from trpc to features/slots (#25538)

Move handleNotificationWhenNoSlots.ts and its test file from
packages/trpc/server/routers/viewer/slots/ to packages/features/slots/
to resolve circular dependency issue where packages/features imports
from packages/trpc.

This file is not TRPC-specific and belongs in the features package.
