Create a fresh static change address for fractional loop-ins and persist
its key locator with the selected HTLC outpoint. Recovery reconstructs
the same change output instead of returning funds to the legacy root
address.
Join each selected deposit with its persisted static-address row during
loop-in recovery. Hydrate legacy rows as needed so restored swaps retain
the scripts and key locators required for signing.
Add schema, sqlc queries, store fields, and SqlStore support for
recording server confirmation-risk decisions with static loop-in swaps.
Store the decision timestamp so payment-deadline recovery can
reconstruct elapsed time after restart.
