Fix all code review issues in pre-draft rankings feature

- Replace useFetcher with direct fetch() for add/remove/reorder so rapid
  clicks no longer cancel in-flight requests
- Add toast.error() on all failure paths (matching live draft room pattern)
  and revert optimistic state when operations fail
- Add useRef to give handleReorder a stable reference without a localQueue
  closure dependency, preventing unnecessary QueueSection re-renders
- Convert allPlayersPanel and rankingsPanel to useMemo
- Remove leagueId from loader return; read from useParams() instead
- Extract queueBuilderHref to a variable in the league home component
- Add emptyMessage prop to QueueSection with a correct message for the
  pre-draft context ("Add players from All Players...")
- Add draft-queue-access.test.ts covering all loader access control paths:
  401/403 errors, status-based redirects, and redirect URL correctness
