Currently on master the qml fee histogram colours are calculated for feerates clamped to [1, 600] sat/vbyte. I want to extend it to now cover [0, 600] sat/vbyte.
I would like to extend it in a way that does not change the existing colour meanings/mapping, so not just e.g. doing an offset.

Even though the exception dialog inherits from ElDialog the padding
didn't work as it overwrites the properties of the ElDialog. So the
padding has to be applied separately to the ExceptionDialog.
binds the walletCanReceive variable to the available inbound liquidity
so the withdraw button gets enabled when the channels reconnect if the
user opens a lnurlw request dialog before the channels have connected.
separates the resolving step from the QEInvoiceParser so the 'recipient'
can be resolved first and then either an QEInvoiceParser can be used if
it is a sending request that has been resolved (invoice, address,
lnurlp, ...), or RequestDetails can be used if the resolved 'recipient'
turns out to be a voucher/LNURLW string.

adds handling of lnurl-withdraw payment identifiers which allow users to
withdraw bitcoin from a service by scanning a qr code or pasting the
lnurl-w code as "sending" address.
add some padding at the bottom of the LoadingWalletDialog so the
spinning circle is not directly at the bottom of the dialog, looks a bit
nicer this way.
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.
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.
deletes the `seed_type` key from `wizard_data` in `WCWalletType` if it
is not explicitly set to prevent a stale value from a previous wizard
flow if the user goes back in the wizard and selects a different wallet
type instead of completing the wizard with the previously selected
wallet type.
This happens as the `apply()` function gets called with the
previously set radio button (e.g. 2fa) if the user goes back, if he then
selects multisig the `2fa_segwit` `seed_type` won't get cleared and
cause the exception later.
Example exception when first selecting 2fa, then going back and creating
a multisig wallet:

when setting a transaction label in the qml
`LightningPaymentDetails` or `TxDetails` dialogs which get opened
directly by the `ReceiveDialog` (`onRequestPaid`) the label is not applied on the main
transaction list as no callback for `detailsChanged` is registered which
gets called when the label changes. As a result the label is only
visible after the main list gets reloaded (e.g. restart).
This commit adds callbacks for `detailsChanged` to fix this.
- makes it consistent between the qml and qt guis that now both show the hex pubkey
- previously qml was showing npub
- don't truncate to first 10 chars, as that's still easy to bruteforce
- the qt gui has space to display the full pubkey (64 hex chars)
and can use the TreeWidget's columns to truncate as needed
- qml has less space, truncate to 32 hex chars there (128 bits should be enough against bruteforce)
changes qeswaphelper to shate a single, long lived transport instance
instead of opening new transports to do swaps and fetch offers.
This allows to continuosly fetch offers, so events which get returned
later by slow relays don't get missed and the fee values stay updated.
Also fixes a race causing the list to miss some swapservers, as the
current implementation fetches only until
`swap_manager.is_initialized()` is set, which will get set as soon as an
event of the configured swapserver is received. So if the event of the
configured swapserver is received as first, all server events coming in
after it would get ignored.
Previously the server parameters were each handled differently, e.g. auto-connect was only applied when updating Network.server
and not when Config.autoConnect was updated. Similarly, updating Network.server did not restart the network, leading to >1 connection
when Network.oneServer was set to True before updating Network.server.
Consolidate server parameter updates into a single call, remove the individual setters, and move Config.autoConnect and Config.autoConnectDefined to Network.
