Remove redundant lost-and-found warning log

[masenf]

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.

Greptile Summary

This PR removes a redundant console.warn in emit_update that fired whenever emit_lost_and_found returned False. Both failure paths inside that method already emit their own log messages (console.warn for a missing Redis token owner and console.error for a Redis publish error), making the outer warning a duplicate that added noise without actionable information.

• Removes the if not await ... guard and its console.warn("Failed to send delta to lost and found for client …") in reflex/app.py, leaving a plain await call.
• No behavioral change: failures are still logged at the correct level inside emit_lost_and_found and _get_token_owner; the boolean return value of emit_lost_and_found is now ignored since there is nothing to act on at the call site.

Confidence Score: 5/5

Safe to merge — the removed warning was purely cosmetic and every failure case remains logged inside the callee.

The change is a four-line deletion of a warning that duplicated existing log output. All failure modes in emit_lost_and_found and _get_token_owner continue to log their own messages, so observability is unchanged. There is only one call site, no test regressions to worry about, and no behavioral change.

No files require special attention.

Important Files Changed

Filename	Overview
reflex/app.py	Removes a redundant console.warn that duplicated logs already emitted inside emit_lost_and_found; the return value (bool) is now discarded but that is consistent with no action being needed at the call site.
