Code review fixes: type safety, security hardening, and dead code removal

- Fix Socket.IO event types: draft-paused and draft-resumed were typed as
  () => void but are emitted with { seasonId, paused } data payloads

- Fix draft.force-manual-pick: add missing season.status === "draft" guard
  so commissioners cannot force picks outside an active draft; add duplicate
  pick-number check so a slot cannot be assigned two picks (the previous
  code only checked participant uniqueness, not slot uniqueness)

- Replace args: any with ActionFunctionArgs / Route.LoaderArgs across all
  API routes and league loaders; replace (auth as any).userId casts with
  proper const { userId } = await getAuth(args) destructuring

- Remove unused isSnakeDraft = true dead variable from draft.make-pick

- Replace autodraftSettings: any and draftSlots: any[] in draft-utils with
  properly typed InferSelectModel / DraftSlot types

- Update force-manual-pick tests: sequence draftPicks.findFirst mock for
  the two-call flow; add new tests for status-check and slot-uniqueness
