Make historic COTD Match Info more accessible

[Satamari]

It is currently quite inconvenient to find the Match Info Pages of old COTDs. Would it be possible to add a button on the TOTD overview page and/or the individual TOTD page that takes you to the (main) COTD results page?

Once on the main run COTD page, there could be further buttons to access the reruns/main run of that same map.

Another solution could be to enhance the COTD overview page to have navigation buttons to go month by month like the TOTD overview.

Much like the other way around, there's no direct way to retrieve a map's COTD competitions afaik. In that case we can at least access any given month's set of TOTDs, but it's not as simple for TOTD->COTD.
COTDs are effectively just identified by their name amidst thousands of other competitions, so it's not easy to find them if you only know the date.
Needs some more investigation, but I think at least the link to the main COTD might be doable using Jonese's data.

I wonder if it makes sense for us to store these map->COTD connections in our own database to avoid a potentially slow third party API call
