Make the funding instructions so easy a drunk caveman could do it confidently

I was reviewing the getting started docs to add funds to my Odyssey account and noticed some helpful updates. That said, the process was still a bit unclear.

Please ensure the guide walks through every step—from funding to confirmation—with clear screenshots. Right now, it ends at the QR code, but users unfamiliar with the process won’t know what happens next. Show that they’ll send funds to the QR/wallet address, receive a confirmation, and then see their balance reflected on Odyssey.
