add new param current_status to /api/order cancel

[jerryfletcher21]

What does this PR do?

This PR introduces a new optional parameter current_status that can be used when cancelling an order. The server checks if current_status is the correct status of the order and returns an error without cancelling the order if it is not. This way a client can be sure to cancel an order just if the status is the one it specified. Fixes backed and tests of #1311.

This PR is solid and complete. We will be merging #1326 instead given that it implements the frontend fixes and has integration tests as well. But a few things from this PR can be implemented there for the best of both worlds 😄

Makes sense to split the reward as discussed on #1326. Please post an invoice for 40K Sats (+ week expiration if possible) 🚀

Closing.

Sure, perfectly fine with me, I left some comments in #1326
