- use SetMinimumSize instead of sizeHint
(partially reverts 28f794b63b)
- to deal with small window sizes, set MinimumHeight of the
parent TabWidget (with a few extra pixels for margins)
- add an extra layout around address_help_text, so that it has
margins (margins were removed in 28f794b63b)
Previously the receive_tabs widget was allowed to be much smaller
than its inner main widget (e.g. truncating visible QR code).
A bit hackish to overwrite/monkeypatch sizeHint,
but I've tried a few approaches and this seems to work best.
Disable rebalance/swap suggestions attached to requests/invoices if there is an ongoing task.
Note: This assumes that all tasks are lightning payments, which is true for the moment.
These methods return a list of channels that can be rebalanced,
in order to receive or send a given amount.
Also add 'channels' parameter to submarine swaps.
Previously, swaps were not considering which channel to use.
When we do not have liquidity to pay an invoice:
- add 'rebalance' option in order to pay an invoice
- use the suggested channel in the 'swap' option
When we do not have the liquidity to receive an invoice:
- add 'Rebalance' and 'Swap' buttons to the receive tab
I believe lightning requests created before https://github.com/spesmilo/electrum/pull/7730
can have an amount of None - ones created after have amount 0 instead.
We could do a wallet db upgrade potentially.
Regardless, the type hint is `get_amount_sat(self) -> Union[int, str, None]`,
so None should be handled. (well, arguably "!" should be handled too...)

InvoiceList.update() calls hide_if_empty(), which calls setVisible().
setVisible(True) should not be called before the widget is properly parented and put into a layout,
as that results in a blank window flashing up (appearing and disappearing) briefly.
