Report number of discarded log bytes in client report

[adinauer]

📜 Description

When discarding logs we now report the number of bytes discarded in Client Reports.

💡 Motivation and Context

Since discarded log count is not shown in UI, we want to track discarded bytes too.

💚 How did you test it?

Bug: Inconsistent Lost-Event Handling for LogItem Envelopes

When a LogItem envelope item is lost but envelopeItem.getLogs() returns null (e.g., due to deserialization failure), no lost event is recorded. This is inconsistent with the Transaction handling (lines 91-103) which always records the transaction as lost even when getTransaction() returns null. The LogItem case should record at least 1 lost item when logs is null, similar to how other item types are handled in the else block (lines 111-113).
