Preserve send-to-all routing in dedicated mode

[BenCodez]

Summary

• preserve SendVotesToAllServers exactly as configured when DedicatedVotingProxy is enabled
• make the routing policy explicit: dedicated presence changes only the source of player/server state, not vote fan-out
• keep backend reward behavior and existing PerServerRewards storage handling independent of proxy routing
• add a regression test covering both enabled and disabled fan-out in dedicated mode

Validation

• git diff --check: passed
• GitHub Java CI will validate the branch
