Fix local cluster tests broken by quic client and remove #[ignore] annotations

[willhickey]

Problem

These local cluster tests are failing as a result of setting DEFAULT_TPU_USE_QUIC = true which enables quic client (see PR #26927).

• local-cluster/tests/local-cluster.rs

  • test_local_cluster_signature_subscribe
  • test_forwarding - Fixed in PR Fix test_bench_tps_local_cluster_solana #27448
  • test_snapshot_restart_tower - Fixed in PR Fix test_bench_tps_local_cluster_solana #27448
  • test_votes_land_in_fork_during_long_partition

• local-cluster/tests/local_cluster_slow_1.rs

  • test_fork_choice_refresh_old_votes
  • test_switch_threshold_uses_gossip_votes

• local-cluster/tests/local_cluster_slow_2.rs

  • test_ledger_cleanup_service - Fixed in PR Fix test_bench_tps_local_cluster_solana #27448

Notes

Similar failures in other tests caused by port mismatches between client and server (PR #27046) and address mismatches (0.0.0.0 vs 127.0.0.1) ( PR #27071 and #27096)
