[client] Add GetSelectedClientRoutes to route manager and update DNS route check (#5802)

- DNS resolution broke after deselecting an exit node because the route checker used all client routes (including deselected ones) to decide how to forward upstream DNS
  queries
  - Added GetSelectedClientRoutes() to the route manager that filters out deselected exit nodes, and switched the DNS route checker to use it
  - Confirmed fix via device testing: after deselecting exit node, DNS queries now correctly use a regular network socket instead of binding to the utun interface
