jif 4be9cfdf30 Improve diagnostics for compressed rollout read failures (#55545) ...

## Why

Undecodable compressed rollouts need diagnostic details and their original bytes preserved for investigation.

## What changed

- Log compressed file size, first-frame content size, decoded byte count, and whether the open file changed when a compressed rollout read fails. Limit warnings to once per process per minute and exclude paths and contents.
- Allow diagnostic reports to attach the raw `.jsonl.zst` archive after a decoding failure when no preferred plain rollout exists. Retain attachment size limits and append `.zst` to filename overrides when needed.

## Testing

Add coverage for truncated streams, incomplete trailing frame headers, files truncated after opening, and diagnostic uploads that preserve undecodable archives with size limits and filename overrides.
