fix: More detailed monitoring of the epoch handover to AVS [WPB-19989]

[EnricoSchw]

WPB-19989 [Calling] Epoch Update not passed on AVS

Description

When passing the epoch information to AVS, we notice significant things.

• Epochs are much larger than the join/leave events would expect.
• Epoch updates are not always passed to AVS.
• Different clients send with different epochs.

To narrow down the cause, we are monitoring the epoch generation and forwarding to the AVS SDK.
