Why Did They Bake The Bread Now? - Pekudei 5769

When the Torah lists the things that were made in Parshas Pekudei, in 39:36, one of the things that are listed is the (אֶת-הַשֻּׁלְחָן, אֶת-כָּל-כֵּלָיו, וְאֵת, לֶחֶם הַפָּנִים). Why are the (לֶחֶם הַפָּנִים) listed here, they were no different than any Korban?

The Mishkan was built by the 25^th day of Kisleiv and did not start functioning until Rosh Chodesh Nissan, so any (לֶחֶם הַפָּנִים) that were baked at that point would have been old and most probably Posul by the time Rosh Chodesh Nissan came around. So the inclusion of the Lechem Hapanim at this point seems to be very strange. It does mention Shemen by the Menorah and Ketoires by the Mizbaiach Haketoires, however, that is not shver, as we know from Chanukah that Oil was prepared in advance and we know from the Korbanois that the Ketoires was made once a year. Now we learn the Lamed Tes Melachois out of the Mishkan. There is a Machloikes Rashi and the Bahag what that means. Rashi says we only learn the Melachois that were done in the building of the Mishkan. The Bahag as brought by Toisafois says, that we learn from the functioning of the Mishkan as well. One of the Kashas on Rashi is the fact that the Mishnah counts Oifeh (baking) as one of the Melachois, however, baking was not needed in the construction of the Mishkan. Rashi seems to answer that by saying they cooked the Samamanim (dye) that they used to dye the wool. However, this is not satisfying, as the Mishnah should list Bishul (cooking) and not Oifeh (baking), as the dye was cooked. If there would be an answer that would state that the Lechem Hapanim is part of the Binyan Hamishkan, then we would be able to answer the Shittah of Rashi that we learn the Lamed Tes Melachois from the Binyan Hamishkan and despite that fact, the Mishnah counts Oifeh.
