Keep recoverable replay loads visually clean

Current logic replay files can contain a readable prefix when the
server is stopped before MessageWriter.Dispose closes the gzip stream.
Unity still records that diagnostic internally, but successful loads no
longer present it as a scary primary status line. The loaded status is
also shortened so the HUD does not wrap awkwardly after the team/player
numbers.

Constraint: Latest user-provided test replays are readable but end before a clean gzip/protobuf close.
Rejected: Treat recoverable replay tails as fatal | would break playback for current logic-group samples.
Rejected: Modify logic writer in this interface patch | user asked to inspect logic, and interface PRs should avoid logic/ changes.
Confidence: high
Scope-risk: narrow
Directive: Keep incomplete-tail diagnostics internal unless a load has no usable frames or truly fails.
Tested: Unity-Playback WebGL build succeeded.
Tested: Unity-Playback-WebGL.zip contents match playback/ directory by SHA256.
Tested: CDP WebGL regression loaded playback.thuaipb, mygame.thuaipb, and playback (1).thuaipb across repeated, cross-file, during-playback, URL, and blob scenarios with no playback-error or JS exception.
Tested: dotnet format whitespace verify for Unity-Playback scripts; git diff --check; origin/dev PR diff has zero logic/ files.
Not-tested: Manual OS file picker in the user's visible Chrome profile.
