Generate wallet from private view key and remove cashcow/cheatmode

[napoly]

needs clean up.. should resolve the heat up issue as we don't need to wait and we can test the wallet upload workflow (branch from roslyn analyzer - needs rebase as well)

just dropping some info reg the heat up issue:

• during the UI step, the wallet rpc does not have an open wallet (but the test wallet exists)
• the wallet must be opened.
• after doing this, i changed the wallet is synced code to wait for the wallets height to == the daemons height. but originally the daemons height is 0 naturally so the wallet doesnt have to sync.
• i sent a get_address req to pass to generate blocks (100)
• looping until wallet height == daemon height, then the AllAvailable signal is sent correctly after synced = true
• i have added a create_account call after the get_address to try the workflow again but its failing randomly still during build.
  logs of the above @ https://github.com/plowsof/btcpayserver-monero-plugin/actions/runs/15805097781/job/44548796393#step:9:2210
  the wallet rpc is available for requests (get_address .. create_account go through no problem)

a helpful piece of info would be an _logger "hello world" in the UI playright test file just to sanity check that this happens AFTER the above. because - starting wallet rpc up and immediately creating/opening a wallet makes everything work.

confirming:

• heat up issue is because the UI test file does not know about the wallet rpc's status / it does not wait for it to become available
• the wallet will sync during the UI's test execution / in parallel , to explain the 'runs 2nd time' , and why creating a wallet/opening it at wallet-rpc start up in my PR 'fixes' ot (hides the problem)
• UI must wait for IsAvailable

should resolve #27
