jedarden 2d4211938a fix(hedging): implement proper timeout-based hedging for p95 latency 
Fixes the hedging logic to properly avoid slow nodes by using tokio::time::timeout
instead of the previous race-condition-prone tokio::select! approach.

Key changes:
- execute_hedged_request: Use timeout on primary request, then hedge if timeout
- This ensures that when the primary is slow (> p95 * multiplier), we cancel it
  and use the hedge result instead
- Fixed make_test_topology to set groups to Active state (pre-existing bug)

All 4 hedging chaos acceptance tests now pass:
- p5_2_a1: Slow node avoided via hedging
- p5_2_a2: p95 latency close to healthy baseline
- p5_2_a3: max_hedges prevents thundering herd
- p5_2_a4: Writes never hedge

Closes: miroir-uhj.2 (P5.2 §13.2 Hedged requests for tail-latency mitigation)
