It is much easier to reason about the rpcserver if we don't allow changing its basic settings while it is already running. What does it mean to change the TCP port it is listening on ("rpcport") if it's already running? It is even problematic to change the rpcpassword: care needs to be taken to already update it for the current server.
(ref https://github.com/spesmilo/electrum/issues/6762)
This commit disallows changing all of the "rpc*" config variables if the daemon is already running.
---
Simultaneously, it also ensures rpc_password is always set and auth cannot be disabled.
Previously if there was a daemon running, and the user ran
`$ electrum setconfig rpcpassword ""` that would leave the RPC unauthenticated
for the current session. However next time the daemon restarted, get_rpc_credentials would see
the unset password and generate one.
I think this was the worst of both worlds:
- we did not really allow removing the rpc password, except for the current session, and
- perhaps unexpectedly, we would generate a new password on daemon restart
Instead now we explicitly make sure the RPC server can never get into a state where it does not have a password set.

The 2fa secret is not selectable or copyable, this is very inconveniant
when setting up a new 2fa wallet as the user has to somehow manually
write the secret e.g. on a paper to then enter it again in their 2fa
app. This makes the secret string copyable by clicking on it.
Catch NetLegacySinglesigScriptType and convert it to a
UserFacingException if the user tries to import a private key for which
it is not possible to get a singlesig descriptor (e.g. p2wsh).

- could not find a single project that still actually cares about bip70 [0]
- well except maybe BitPay.
- but I cannot test with BitPay:
- they have a testnet3 staging environment on test.bitpay.com
- but the SSL cert they use for bip70 has expired in 2021
- the webUI probably also has not been updated since then...
- they claim to have added LN support in 2022 in a blog post,
but it's not there on test.bitpay.com
- on mainnet, they require KYC before payment
- < ... angry noises >
- their loss then, I don't care.
- this is code that no one wants to maintain
- this does not yet delete the signed bip70 payment data for historical txs
- but it is no longer possible to export it from the GUI

As it's failing due to relative imports, this might have been broken since py2->py3 migration.

The `until` filter would limit the relay to only send us events created
up until this timestamp. If the user opens a swap transport by opening
the swap dialog, and keeps the dialog open the dialog will naturally age
above this limit and the relay will stop sending the client swapserver
events as they have (legitimately) been created after this timestamp.
As sanity check we still have the comparison against the current
timestamp in the event parsing loop to prevent pre/backdating.

Non-Ascii characters should not be converted for
checksum calculation.
This will give consistent hash to BIP-128 and its
Javascript code example.
Timelock-Recovery Plans that contained only ascii
characters are not affected.
Also, 8 hex-chars is enough for a checksum.
The typical flow of an update is:
---UPDATE--->
--- SIG --->
<--REVACK----
<-- SIG ----
---REVACK--->
It makes sense to try to send a sig ("commitment_signed") right after we send an update.
It also makes sense right after we send revack.
Besides those times, we could call "maybe_send_commitment" at *any* time, that is safe, and depending on other call locations, it might be an optimisation, however it is not needed.
In particular it is unclear why we had those calls when we *receive* updates (and only for certain types of updates - not consistently).
I moved my node to standard port again because the non-standard one was apparently used by malware. I also updated the domain name (both work at the moment, but I prefer the shorter one).
