user on bitcointalk [0] tried to create wallet with name "w/o 2FA".
Before this, one would only get an error after the last page of the wizard.
With this, the "Next" button does not even get enabled if the name does not look ok.
(and as in comment, maybe we should be even stricter re what is allowed)

- rename globals
- also rm hardcoded strings from qml
- use consistent unit names in qml
(previously mixed sat/vB and sat/byte (latter coming from core lib))

This is a bit ugly, but activeFocus is declared as final and cannot be overridden directly...

```
I am only making this change as it makes it simpler to do manual testing of CPFP-ing *local* txs.
That is, by changing a few easy-to-find lines of code, I can make the GUI allow CPFP-ing a local tx, but
without this change it errors out with "unknown fee for parent transaction".
If one has an incoming local tx saved in the wallet, adb.get_tx_fee(txid) returns None
(if the tx gets into the mempool, it will use the server-reported value instead).
In contrast, wallet.get_tx_info(tx).fee calls both wallet.get_wallet_delta(tx) and adb.get_tx_fee(txid),
making it more expensive but more complete.
On Android, we disallow screenshots on screens where the seed is visible.
(The seed is extremely sensitive data that should not be stored digitally without
significant precautions but it's also cumbersome to write down or memorise, so
some people instinctively just try to take a screenshot of it when creating a wallet.)
We do this by using the built-in OS mechanism of setting FLAG_SECURE on the window.
However, on some devices with custom ROMs (one report from LineageOS, one from /e/OS),
unsetting FLAG_SECURE crashes the application for some reason.
As a workaround, this commit adds a config setting into the Preferences,
to disable this mechanism and just always allow screenshots.
(note that you can get into the qml Preferences before creating/opening any wallet)

- risk_of_burning_coins_as_fees is turned into a private (helper) method, only called by check_sighash.
UIs should only care about check_sighash.
- check_sighash returns instance of new class "TxSighashDanger" instead of tuple
- made warning levels more fine-grained (FEE_WARNING_SKIPCONFIRM vs FEE_WARNING_NEEDCONFIRM)
- this became more complicated than I had hoped for but I think it is worth it to ~merge
check_sighash and risk_of_burning_coins_as_fees into one.
