B897 Server-Side Fixes

B897 Server-Side Fixes is a small server-only Harmony mod that patches a handful of gameplay/replay edge cases in Puck B897. Fixes included: - Replay ghost object cleanup Cleans up orphaned replay objects after replays end, including replay player bodies, cameras, stick positioners, sticks, and replay pucks that can otherwise remain in the scene. - Replay restart cleanup Fixes an issue where starting a vote/start command during an active goal replay could leave replay objects visible and still animating. The mod now stops the active replay cleanly before restarting the game flow. - Faceoff double-click protection Prevents a player from rapidly double-clicking the same faceoff position and accidentally triggering duplicate position handling that can create bad player body state. - Zero-second pregame faceoff fix Supports servers that set pregame duration to 0. The mod ensures the play timer is still initialized correctly before faceoff ends, preventing the first start from immediately jumping to intermission. This mod is intended for dedicated servers.
