Remove redundant lost-and-found warning log (#6527)

* Remove redundant lost-and-found warning log

The warning "Failed to send delta to lost and found for client" was
duplicative — emit_lost_and_found already logs the underlying cause
(either "Redis token owner not found" or "Redis error publishing
lost and found delta") for both failure modes. The extra warning
wasn't actionable and confused users.

* Remove redundant Redis token owner not found warning

This warning fired whenever a token wasn't registered in Redis, which
can happen normally (e.g. expired tokens). It wasn't actionable and
confused users.
