Add Voting Last Days template for Combined model

An E-mail template for the previously missing voting_last_days
message when in a combined model election. Also adjust the poll_name
replacement macro for the more verbose TC poll name used this cycle,
and switch the reference_url replacement macro from Gitea's raw view
to its normal code browsing view.
