gamer147 0ecd565774 fix(arena-tk2): park returns 3002 RETRY + empty node_server_url ...

Two client-crash bugs in the do_matching response when no partner is
waiting:

1. matching_state was 3001 (RC_BATTLE_MATCHING_ILLEGAL); the client's
   Matching.OnFinishedDoMatching switch maps that to an error dialog,
   not a retry. The retry state is 3002 (RC_BATTLE_MATCHING_RETRY).

2. node_server_url was omitted entirely. The client's
   DoMatchingBase.SettingDoMatchingData reads it via
   data["node_server_url"].ToString() with no Keys.Contains guard, so
   absence throws KeyNotFoundException out of NetworkManager.Connect
   before the matching_state switch is even reached. Prod RETRY
   captures send "" while waiting and the real URL only on SUCCEEDED;
   match that.

battle_id stays absent; its accessor IS guarded.
