Bugfixes

• Fixed infinite retry loop when a configured video path is invalid or not found — the condition is now discarded after the first failed attempt and stops retrying until the next session
• Fixed gamemode toggle spam caused by notifyFirstJoinVideoState(true) being sent before path validation — the server is now only notified when playback actually starts
• Fixed session consumed key being written before confirming the video path exists, which was incorrectly burning a non-repeatable condition even when the video failed to play
• Removed duplicate registration of CLIENT_VIDEO_REQUEST_PACKET receiver in ConfigSyncNetworking.init()

Improvements

[Network]: Manifested video paths from the server are now tracked client-side; if a video is pending download, the client correctly retries instead of discarding the condition as invalid

[Server]: Server now logs a warning when a configured video file is missing from its filesystem at manifest build time, giving server operators visibility into broken paths without burdening clients

[Network]: Client no longer reports "invalid or not found" for paths that are legitimately pending a server download
