Reduces the precision of the date field in the qml transaction history
list to minutes. Seconds don't seem very useful in practice and add
clutter to the UI. This adapts the behaviour to the Qt GUI.
When the user has already loaded a wallet in QML and tries to restore a
new wallet `WCHaveSeed.qml` incorrectly shows a `Finish` button instead
of a `Next` button and raises a KeyError if the user clicks on Finish
instead of resolving the passphrase input view (regression from
https://github.com/spesmilo/electrum/pull/10016).
This happens because `last` of `have_seed` depends on
`NewWalletWizard.is_single_password()` and NewWalletWizard.wants_ext(wizard_data).
`is_single_password()` is true if a wallet is already loaded,
while `wants_ext(wizard_data)` is false as `wants_ext()` depends on `seed_extend: True` in
`wizard_data` which only gets set after `apply()` of `WCHaveSeed` gets
called, however the evaluation of `WCHaveSeed` being the last view
happens before the view is shown.
By calling `checkIsLast()` in the validation timer of `WCHaveSeed` the
`last` property gets set again after `apply()` has been called, so
the view is guaranteed to correctly show either the `Finish` or `Next` button
after a seed has been entered.
Handles exceptions thrown by `shutil.copyfile()` in the
`add_plugin_dialog`.
In issue #10101 an user tried to access an onedrive vault directory which
made shutil fail to copy the file with:
```
OSError: [Errno 22] Invalid argument: 'odopen://unlockvault/?accounttype=personal'
```
so that with a feerate of 0.1 sat/vbyte, for a tx of size 141 vbytes, the fee is 15 sat (instead of 14 sat)
(assuming a min relay fee of 0.1 s/b, the tx needs to pay a minimum of 15 sats to propagate)
Adapts the gui(s) to detect if an existing reserve input has not been
used as input for the transaction even though the user tried to spend
max. This allows to show the lightning reserve warning not only for
reserve change outputs but also for existing reserve inputs that have
been ignored for this max spend transaction.
Still keeps the `is_utxo_reserve` flag on `PartialTxOutput` as it is
used in the qml gui.
qml: add signals for QEQRScanner and fallbacks, add QEBytes container type
so we can pass along byte arrays between QML and python, port qr scan
occurrences to new signals.
Removes the '.desktop' suffix from the
`QGuiApplication.setDesktopFileName` argument to prevent the following
warning on startup of Electrum:
```
QGuiApplication::setDesktopFileName: the specified desktop file name ends with .desktop.
For compatibility reasons, the .desktop suffix will be removed.
Please specify a desktop file name without .desktop suffix
```
The [qt
docs](https://doc.qt.io/qtforpython-6/PySide6/QtGui/QGuiApplication.html#PySide6.QtGui.QGuiApplication.desktopFileName)
say that `desktopFileName` is "... is the file name, without the full
path or the trailing “.desktop” extension of the desktop entry that
represents this application according to the freedesktop desktop entry
specification."
When putting app to background with qr scanner active, then moved to foreground again,
SimpleScannerActivity instance is not destroyed, but the local mScannerView was re-initialized
with a new instance (through startCamera()) regardless of pre-existing instance, and added to
the contentFrame. This leaves the previous mScannerView instance in limbo, potentially getting
garbage collected at unpredictable times.
Adds an on_done_callback to the QESwapHelper.transport_task future
to prevent the task from swallowing exceptions by retrieving exceptions
and calling `util.send_exception_to_crash_reporter` with them.
Do some validation if the user input in `NewChannelDialog` before
allowing to click the `Ok` button. This is done to make the UI a bit
more intuitive and prevent issues like #10053 in which the user was able
to click `Ok` with a empty trampoline node list which raised an
`IndexError` (probably on testnet4).
- don't show crash reporter multiple times for the "same" exception
- at least until the user restart the program (there is no persistence)
- this is a ~replacement for the removed "Never show crash reporter" option
- in case there e.g. a thread with timer spamming an exception erroneously,
this ensures we only offer to send the crash report once (per process lifecycle)

`TxDialog` may has to fetch tx information from the network on
construction (`self.set_tx()`) and is showing a `RunCoroutineDialog`.
If the user cancels this dialog the `UserCancelled` exception is not
caught in `show_transaction()` and can even lead to Electrum crashing.
Fixes#10041
Fixes exception occuring when `wallet.lnworker` is `None` and the user
clicks on `New Channel` in the channels list tab. The `New Channel`
button is enabled when the wallet *can* have lightning, not the wallet
actually having lightning enabled.
With this patch the `init_lightning_dialog` will show up if the user
clicks on `New Channel` but lightning is not yet enabled.
I noticed this by restoring from a funded vpub and then
loading the keystore from seed afterwards.

None before trying to disconnect it.
- save custom fixed feerate fee_policies, not just slider-restricted ones
- dynamically update fee_target text, to follow feerate_e
- otherwise when the slider is set to "feerate", users would be shown two conflicting values
