* Fix divisibility in invoice details of lightning amounts
This PR will show 11 decimal in the invoice details for BTC amount
of lightning payment methods.
It also hacks around the fact that some
lightning clients don't create the requested amount of sats, which
resulted in over or under payments. (Blink not supporting msats, and
strike)
Now, In that case, a payment method fee (which can be negative) called tweak fee
will be added to the prompt.
We are also hiding this tweak fee from the user in the checkout page in
order to not disturb the UI with inconsequential fee of 0.000000001 sats.
* Only show 8 digits in checkout, even if amount is 11 digits
* Rename filter to storeid for consistency with other filters
* Greenfield: Add storeId to notification
* Cleanups
* Greenfield: Allow filtering notifications by store id
