RunCoroutineDialog has a run() method that blocks the thread
without blocking the GUI (using exec), and a Cancel button
that cancels the coroutine.
main_window.run_coroutine_dialog() is a wrapper that returns
the coroutine result and may raise exceptions.
BlockingWaitingDialog was removed is transaction_dialog,
where it was not particularly useful.
I just had a channel force-closed over a fee-estimate-disagreement :(
Scenario:
1. started electrum, opened wallet
2. waited around 10 seconds, opened the lightning channels overview, saw that channels are open/ready
3. after around 10 more seconds, scanned bolt11 invoice and tried to pay
4. channel got force-closed
Before this commit, we only call maybe_update_fee via lnwatcher callbacks.
These callbacks trigger on events such as "adb_set_up_to_date", "blockchain_updated", "network_updated", "fee".
In my case there was a race that all these events triggered *before* the channel got reestablished
(in fact before the peer handshake finished). And also, by chance there were none of these events after
the reestablish but before I sent the HTLC.
When I sent the HTLC, the channel counterparty (eclair) sent back an "error" msg that the feerates are
too different, which led us to do a local-force-close.
I have other channels in this wallet (with other peers), which reestablished faster and got lucky with
timing: the lnwatcher callbacks came just in time to trigger update_fee for them.

yay
Given how few providers have free historical APIs, each one is very much appreciated.
They are doing a public service. Thanks. Not that they ever read commit messages. :)

I will use this in the trezor (and clones) plugins in a modified form to work with qt6.
Otherwise we would have to ask the trezor devs, who would actually respond,
but also the keepkey and safet lib authors, who would not... to support qt6.
There is an issue with plyer on Windows, which I thought was related to the mixed
backwards/forward slashes in the path, but no, this change still did not fix it:

- wallet.get_receiving_addresses is guaranteed to exist (maybe it was only for HD wallets in the past)
- wallet.is_mine is stricter than wallet.adb.is_mine, usually we want the former
