Drop "End of Month Campaign Report" suffix from CTA Campaign headers

CTA phases now get the same plain "TXproducts — {timeframe}" header
every non-branding-campaign period already uses, instead of the
branding campaign's own "...End of Month Campaign Report" phrasing —
the Campaign dropdown above it already names the campaign, no need to
repeat it in the header too.
