Replace get_key_for_outgoing_invoice, get_key_for_incoming_request
with Invoice.get_id()
When a new request is created, reuse addresses of expired requests (fixes#7927)
The API is changed for the following commands:
get_request, get_invoice,
list_requests, list_invoices,
delete_request, delete_invoice
`wallet.make_unsigned_transaction` can raise NotEnoughFunds or NoDynamicFeeEstimates.
These are "expected" exceptions that need to be handled or worked around. Added a note
of this in the docstring now.
We now handle NoDynamicFeeEstimates by allowing a static fallback fee in
`wallet.can_pay_onchain` and `lnworker.suggest_funding_amount`. It should be
fine to have a static fallback in these cases, as the user still has a chance
to set their own fee later in the flow.
(though ofc the static fallback might be too high in some mempool conditions,
in which case e.g. can_pay_onchain might return a false-negative, but this
is still an improvement over raising I believe)

So that the two methods are consistent with each other.
As concrete motivation, see e.g.
- how the `getrequest(key)` command calls `wallet.get_request(key)`, and
- the `delete_request(address)` command calls `wallet.delete_request(address)`
The _receive_requests dict is keyed by either 'address' or 'rhash' (see get_key_for_receive_request):
- 'rhash' is used if `req.lightning_invoice is not None`
- address is used otherwise
The `get_request_by_address` method was quite error-prone: it only worked for requests that had an LN part...
fixes https://github.com/spesmilo/electrum/issues/7919
In the past, when creating payment requests, we keyed them by on-chain address,
and set/saved the msg of the request as label for the address.
Many places in the code were calling wallet.get_label(addr) with the expectation that
relevant payment requests are found and their message/description (if any) is considered.
wallet.get_label(key) is now made private, and instead the explicit non-polymorphic
wallet.get_label_for_{address,rhash,txid} alternatives should be used.
As the GUI allows saving such invoices, CLI should not break for these wallets.
Also note the pre-existing assert on the next line.

There is some duplication between `wallet.get_onchain_request_status` and `wallet.is_onchain_invoice_paid`
(both in terms of code, and conceptually). `get_onchain_request_status` is used for incoming invoices (receive requests),
and `is_onchain_invoice_paid` is used for outgoing invoices. I think `get_onchain_request_status` existed first,
but as it uses txi/txo, it only works for ismine addresses, so `is_onchain_invoice_paid` was added later
(along with a `get_prevouts_by_scripthash` and corresponding new persisted data structure) to handle the non-ismine
addresses corresponding to outgoing invoices.
I think we could just merge the two functions together... (?)
and this PR does that.
Note in particular that check_password_for_directory was not safe to use while the daemon had wallets loaded,
as the same file would have two corresponding Wallet() instances in memory. This was specifically handled in
the kivy GUI, on the caller side, by stopping-before and reloading-after the wallets; but it was dirty to
have the caller handle this.
get_unused_addresses() has been broken since #7730, because
addresses are considered as permanently used if they are in
the list of keys of receive_requests. This is true even if
an address is used as fallback for a lightning payment. This
means that the number of lightning payments we can receive
is constrained by the gap limit.
If a payment succeeds off-chain, we want to be able to reuse
its fallback address in other requests (this does not reduce
privacy, because invoices already share the same public key).
This implies that we should not use the onchain address as key
for lightning-enabled requests in wallet.receive_requests. If
we did, paid invoices would be overwritten when the address is
reused. That is the reason for the wallet_db upgrade.

- add new index: requests_rhash_to_key (fixes#7845)
- when creating a request, do not save its description in labels.
Instead, return it as default value in wallet.get_label_by_rhash
lnworker:
- rename 'payments' to 'payment_info'
- add note to delete_payment_info
commands: rename 'rmrequest' to 'delete_request'
