   Fixes #30247

   I don’t think this implicit cast can lead to any bugs, so make it explicit to silence the fuzz integer sanitizer.

   Can be tested with:

   0FUZZ=wallet_bdb_parser UBSAN_OPTIONS="suppressions=$(pwd)/test/sanitizer_suppressions/ubsan:print_stacktrace=1:halt_on_error=1:report_error_type=1" ./src/test/fuzz/fuzz /tmp/1376869be72eebcc87fe737020add634b1a29533
   

   After downloading the raw fuzz input from https://github.com/bitcoin-core/qa-assets/blob/24c507b3ea6263e6b121fb8dced01123065c44c2/fuzz_seed_corpus/wallet_bdb_parser/1376869be72eebcc87fe737020add634b1a29533
