"18 pixels" is too large when using qdarkstyle on "low" DPI screens, on Windows
(if there is also a high DPI screen connected as another monitor... eh)
- without this, in send tab paytoedit, try_payment_identifier will get called and it will error
df1b9a223c/electrum/gui/qt/paytoedit.py (L153)
- also, in all text fields this used to result in clearing the current text (but now it is kept instead)

With wallet_type=="standard", if the user enters a 2fa electrum seed, the "next" btn is disabled.
This is a regression in the new wizard, the old one used to "redirect" seamlessly.
This commit does not fix this, but at least shows a user-friendly warning message.
Note: would be nice if the wizard redirected automatically, in both directions (2fa->std, std->2fa).
The old wizard implemented std->2fa (probably the more common case hit by users), and had this
warning message shown for the 2fa->std case. Now I am repurposing the warning also for std->2fa.
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)
