payout: treat a malformed ledger block hash as corruption, not as a hash

SetHex() parses whatever hex prefix it finds and stops, so a corrupt
blockHash loaded as a DIFFERENT hash: garbage with a hex-looking prefix
became a hash no block ever had, which the orphan check reads as an
orphaned block -- and the next flush voided the debt on the strength of
file corruption. Garbage with no hex prefix became 0 and skipped the
orphan check instead. A field that is not the 64-digit hex string this
tree writes now fails the load, and the file is quarantined like any
other parse error.
