fix(failover): improve cache cleanup for provider health and circuit breaker

- Use removeQueries instead of invalidateQueries when stopping proxy to
  completely clear health and circuit breaker caches
- Clear provider health and circuit breaker caches when removing from
  failover queue
- Refresh failover queue after drag-sort since queue order depends on
  sort_index
- Only show health badge when provider is in failover queue
