Changelog-None: The value WALLY_SATOSHI_PER_BTC * WALLY_BTC_MAX is equal to 2.1e15, which is much higher than the maximum capacity of a u32, which is 4.29e9. Hence, use a u64 to store this value instead.
Change in the fuzzing scheme of `fuzz-close_tx` led to the discovery of test inputs that result in greater in code coverage. Add these inputs to the test's seed corpus.
