fix(spend-logs): preserve no-traceback behavior for update_daily_tag_spend

This call site previously logged a single-line error via verbose_proxy_logger.error()
with no traceback. Switching it to spend_log_error(..., exc=e) caused a full stack
trace to render by default (when LITELLM_SUPPRESS_SPEND_LOG_TRACEBACKS is unset),
which contradicts the PR goal of leaving default behavior unchanged. Revert this
specific site to the original error log call.
