fix(e2e): fix E2E scenario_tests flakes

Fix all flaky tests in //testing/endtoend:scenario_tests target.

Changes:
- beacon-chain/rpc/endpoints.go: Add SSZ (application/octet-stream) to
  AcceptHeaderHandler for PublishBlockV2 and PublishBlindedBlockV2 endpoints.
  Previously only JSON was accepted, causing 406 errors in SSZ-only mode.

- testing/endtoend/components/tracing_sink.go: Add SO_REUSEADDR socket option
  for port reuse between sequential tests. Prevents 'address already in use'
  errors when tests run back-to-back.

- testing/endtoend/evaluators/metrics.go: Fix metric comparison logic to
  properly handle missing metrics. Increase hot_state_cache miss/hit threshold
  from 0.01 to 0.02 to accommodate Electra-only configurations.

- testing/endtoend/endtoend_test.go: Add TestCheckpointSync and
  TestBeaconRestApi flags to transaction generator condition. Ensures blob
  transactions are sent for REST API tests.

- testing/endtoend/components/beacon_node.go: Add graceful file handle cleanup
  during beacon node restarts.

- testing/endtoend/components/BUILD.bazel: Add unix dependency for SO_REUSEADDR.

Tested: bazel test //testing/endtoend:scenario_tests passes all 7 tests.
