Use strict txid parsing when reading swap updates and static address
loop-ins from SQL rows. Empty swap update txids still mean "absent",
but any non-empty truncated value now fails loudly.
Add store-level tests that inject truncated txids through the query
layer and assert that the fetch paths reject them.
since deposits have been normalized in the db in the
context of a static address swap this commit now
retrieves the deposit information as part of
GetLoopInByHash and GetStaticAddressLoopInSwapsByStates.
