fix: validate swap out invoice before payment (#2536) 
Verify the invoice returned when creating a swap out before storing and
paying it:

- the invoice payment hash must match the payment hash of the locally
  generated preimage
- the invoice amount must not exceed the requested amount plus the
  quoted service and miner fees (with a small rounding tolerance)
- the lockup address is checked against the swap tree, matching the
  checks already performed for swap in and refunds
- the invoice is verified again directly before it is paid

Also renames AlbySwapServiceFee to AlbySwapServiceFeePercentage for
clarity.
