In this sentence, "will" expresses certainty and determination about the future. It’s similar to saying, "No matter what happens, we are confident that we can handle it." It’s not just intention (like "I will do this"), and it’s not strictly about ability either. Instead, it's a strong assurance that things will be managed successfully.

"we'll" is a contraction for "we will". Whatever happens, We will make it work. I hope this helps. Let me know if you need a more in depth explanation.
