[Medium][Important] Create an MP page just like the resources page (start it with no MPs yet)

[Lumi-works]

I set the MP 1 block to be displayed when its "2024-09-06 09:00:00" CST; same for mp2 and mp3 but with a fake date const targetDateTimeMP1 = new Date("2024-09-06T09:00:00-06:00");

I also set up the MPs nav link to be shown in the header when the time is after 2024-09-06 09:00:00 CST.
